VARIO Chemistry Pumping Units
PRODUCT OVERVIEW
VACUUBRAND GMBH + CO KG offers worldwide the most comprehensive product range of customeroriented laboratory and instrumentation vacuum pumps, gauges and controllers for rough and fine
vacuum. The product range comprises high-performance rotary-vane pumps, oil-free diaphragm
pumps, well-proven pumping units, flexible vacuum systems and solutions for local-area networks.
The range is completed by a wide choice of KF fittings and accessories as well as vacuum gauges
and controllers for rough and fine vacuum. In recent years, local-area vacuum networks with
pumps combining high-performance mechanics and the latest electronic control technology have
gained more and more importance. The design of VACUUBRAND products is driven by our
customers’ requirements.
Rotary-Vane Pumps
VARIO Diaphragm Pumps
VACUUBRAND rotary-vane pumps are designed for
an ultimate vacuum in the range of 1 mbar to
10-1 mbar (one-stage) or 10-3 mbar (two-stage).
The wide range of models available allows to meet
both technical and economic criteria. Selection of
the appropriate pump depends upon the requirements of the application, such as volume flow
rate, pumping speed and ultimate vacuum.
VARIO diaphragm pumps automatically find the
appropriate vacuum level and independently
adjust it with precise single-point control.
The Chemistry Version offers fully automatic
adaptation of the vacuum to the actual process
parameters.
VARIO diaphragm pumps in Aluminium Version
are both modern stand-alone or backing pumps
with adaptive pumping speed, fast evacuation
times, low ultimate vacuum and long lifetime.
For reliable operation and low maintenance of
rotary-vane pumps, we recommend some useful
accessories (see page 19 ff).
The Chemistry Hybrid Pump is a combination of
a rotary-vane pump and a chemistry diaphragm
pump, specially designed for use with corrosive
and condensable gases and vapours.

PRODUCT OVERVIEW
Diaphragm Pumps
Diaphragm pumps are totally oil-free mechanical
vacuum pumps. VACUUBRAND diaphragm pumps
offer, depending upon model, an ultimate
vacuum from < 80 to 0.3 mbar (60 to 0.2 Torr)
and pumping speeds from approx. 1 to 12 m3/h
(0.8 to 7.6 cfm). They often are the best available vacuum system within the laboratory or as
backing pumps for modern wide-range turbo
pumps. For use with chemicals and condensates,
the gas-contacted parts of the diaphragm pump
can be made of corrosion-resistant materials.
Two basic designs are available:
The Aluminium version is designed for a wide
variety of vacuum applications not involving
corrosive media in laboratories and process
plants.
In the Chemistry version, all gas and vapour
wetted parts are made from appropriate
chemically resistant fluoroplastics.
VARIO-SP Diaphragm Pumps
VARIO-SP diaphragm vacuum pumps combine
minimum dimensions and highest performance by
using an electronically controlled brushless 24 V
DC motor. The electronically controlled direct
drive is maintenance-free and has a variable
speed over a wide range. Generally they are
dedicated as system pumps (SP = SystemPump)
for larger systems, e.g. leak detectors, gas
analysers, the regeneration of cryo pumps, and
backing pumps for wide-range turbomolecular
pumping units. The 24 V DC motor with its very
compact dimensions permits mounting in any
position and world-wide operation independent
of different mains voltages.
ATEX Diaphragm Pumps and Gauges
VACUUBRAND offers ATEX chemistry diaphragm
pumps of equipment category 2 (e.g. for zone 1).
Due to the high chemical resistance of wetted
materials, the absence of gliding surfaces, and
the hermetic sealing of the pumping chambers,
they offer an excellent basis for avoiding ignition
sources. ATEX Chemistry Vacuum Systems and
gauges complete this range of products.
PRODUCT OVERVIEW
Chemistry Vacuum Systems and
Chemistry Pumping Units
VACUUBRAND chemistry pumping units are
designed for rough, fine and high vacuum.
Thereby the most appropriate vacuum pump can
be selected as the core component for achieving
the desired vacuum level. For reaching the
maximum performance in various applications, it
makes sense to use a proven configuration, i.e. a
complete chemistry pumping unit. This ensures a
good fit of the required accessories. Chemistry
pumping units offer the advantage of being ready
for use upon receipt.
A multitude of configurations and material options provides a practical and economical solution for nearly every application.
Local-Area Vacuum Network VACUU·LAN®
VACUU·LAN® as a modern vacuum supply for
laboratories is a flexible und cost-saving multiuser solution for vacuum generation in chemistry
laboratories. The range of VACUU·LAN® modules
comprises a series of different types for shut-off,
vacuum control or air admittance.
Vacuum Gauges and Controllers
The demand-driven speed control significantly
reduces the overall work load of the diaphragm
pump. Therefore, the total lifetime of the wear
parts attains previously unmatched values. Noise
level, vibration and power consumption are also
reduced.
Vacuum Valves and
Small-Flange Fittings
The range of VACUUBRAND vacuum valves and
small-flange fittings combines appropriate
standardisation with general practical use.
Dimensions of flange fittings are according to
standards (ISO KF). The range of straight pieces,
T-pieces and cross pieces, pipe elbows, flexible
pipes, couplings, sealing- and clamping rings are
based on the small-flange sizes KF NW 10, KF
NW 16, KF NW 25 and KF NW 40 as recommended
by PNEUROP.
VACUUBRAND operates a government-approved
DKD calibration laboratory. Vacuum gauges in the
measuring range of 1000 to 10-3 mbar (760 to
10-3 Torr) can be calibrated to fulfil the major
requirements of ISO 9000 ff (quality management) and ISO 10012 (quality assurance for
measuring equipment).
Choosing Vacuum Equipment
This section is a practical guide for vacuum
applications in chemistry laboratories. It provides
advice for selecting the appropriate vacuum
system for most applications in your laboratory
including recommendations for environmental
protection.
Vacuum Performance Data
Pumping speeds stated in cfm and l/min are
determined at 60 Hz mains frequency.
Pumping speeds given of diaphragm pumps are
either averaged between 500 and 1000 mbar, or
maximum values (according to DIN 28 432).

Use of Rotary-Vane Pumps
Use of Diaphragm Pumps
Rotary-vane pumps are to be used whenever an
ultimate vacuum down to 10-3 mbar has to be
attained. For a good rotaryvane pump, the pumping
speed should remain
constant over some
orders of magnitude of
vacuum level, and should
not drop down until near
the ultimate vacuum.
Diaphragm pumps are designed for an ultimate vacuum from < 80
to 0.3 mbar (60 to 0.2 Torr). There are two basic designs: Aluminium
and Chemistry (C). In Aluminium, the gas-contacting parts are made
of e.g. aluminium and FPM. Chemistry is specially designed for use
with chemicals and condensates, and the gas-wetted parts of the pump
are made of appropriate corrosion-resistant materials (fluoroplastics).
Due to their flexibility, chemistry diaphragm pumps provide the base
for a multitude of chemistry vacuum pumping units.
Rotary-Vane Pump RZ 6
For applications involving corrosive and condensable gases and vapours at fine vacuum (below
1 mbar), the Chemistry Hybrid Pump RC 6, a
combination of a rotary-vane pump and a
chemistry diaphragm pump, offers many
advantages.

USE OF ROTARY-VANE PUMPS
PUMPING SPEED: ROTARY-VANE PUMPS
Rotary-vane pumps are used where an ultimate
vacuum down to 10-3 mbar has to be attained.
Selection criteria are both the required ultimate
vacuum and pumping speed.
Pumping speeds for VACUUBRAND rotary-vane
pumps are stated, according to PNEUROP, in
m3/h at atmospheric pressure. However, what
counts more in practice is the pumping speed at
the required operating vacuum.
Another important feature is consistently high
pumping speed across a wide vacuum range.
Data for ultimate vacuum always refer to the
pump running at operating temperature.
High vapour tolerance and an efficient gas
ballast system are both important for working
with condensable substances.
The pump is sealed off vacuum-tight at shutdown
to prevent an uncontrolled intake of air or surge
of oil. The special oil circuit shut-off device
minimises corrosion risk during standstill.

The Chemistry Hybrid Pump RC 6 has been designed to minimise the adverse effects of condensable and corrosive vapours. Its main components are a two-stage rotary-vane pump and a twostage chemistry diaphragm pump built of corrosion-resistant materials. The diaphragm pump
continuously evacuates the oil reservoir of the rotary-vane pump in order to keep the partial
pressures of solvent vapours, oxygen and corrosive gases at low level and/or below their
condensation point. The RC 6 is a low-maintenance pump for freeze-drying and other applications
requiring an ultimate vacuum in the 10-3 mbar range.

Oil
Rotary-vane pump oil. . .B
K8
SI 2
Rotary-vane pump oil
Silicone oil . . . . . .
Perfluoropolyether oil
Oil and fluids for rotary-vane pumps have to meet various requirements:
Low vapour pressure, even at elevated temperatures
Excellent lubrication properties
Minimal backstreaming
High thermal stability
Good resistance to ageing
Rotary-vane vacuum pump oil K 8
High oxidation stability
Rotary-vane pump oil K8 is specially designed
for pumping acid vapours. This oil is very hygroscopic and has limited capacity for water vapour.
The alkaline additive is consumed during
operation, making it necessary to change the
fluid regularly, depending on the amount and
type of vapours. When the pump is not used for
prolonged periods, the fluid must be drained
from the pump and the pump must be rinsed
with mineral oil. The vapour pressure and
viscosity characteristics of Oil K 8 will not
provide the same results as Oil B. Pumps may not
reach the stated ultimate vacuum and may not
start up well at low temperatures (< 18 °C).
Oils for rotary-vane pumps
20
OIL FOR ROTARY-VANE PUMPS
STANDARD OIL:
Rotary-vane vacuum pump oil B
Rotary-vane pump oil B is a high-viscosity oil
with low vapour pressure. The high viscosity also
at elevated temperatures ensures good sealing
and long life characteristics for pumping nonreactive gases. Oil B enables good and constant
ultimate vacuum over several weeks even at continuous operation and is used for the first filling
of RE/RZ series pumps.
SPECIAL OILS
Many pumped substances can cause deterioration of common pump oil, leading to mechanical
problems. Special oils should be used as a prevention. In this case, the rotary-vane pump must
be prepared by VACUUBRAND.
Special oils may maintain lubricating properties but only provide limited protection
against corrosion.

Silicone oil SI 2
Silicone oil SI 2 is used when particularly high
ageing stability is required. Because of its chemical composition, this oil is stable against many
aggressive gases – particularly chlorine, hydrochloric acid, and solvent vapours. In addition, it
is largely resistant against most acids.
Synthetic oil (Perfluoropolyether)
These synthetic oils have excellent chemical
resistance and are certified for pumping pure
oxygen. These fluids are used for strong oxidants
(halogenides, nitrogen oxides, etc.). Perfluoropolyether oil will form an emulsion with mineral
oils. Therefore, pumps to be used with these fluids must be free of any mineral oil residues. The
high density of perfluoropolyether limits pump
start-up temperatures to 18 °C or above.

Protect your pump and the environment...
... ON THE INLET SIDE
Cold traps (SKF, GKF)
Cold traps are used to recover
valuable substances*, e.g. from
distillation, or, more frequently, to
protect rotary-vane pumps against
aggressive, corrosive or otherwise
detrimental substances.
* only for pressures < 1 mbar (inlet side)
Separators (AK)
Particles and condensates impair
the operation of rotary-vane
pumps and must be prevented
from entering the pump.
Separators are used to protect vacuum pumps
from particulate matter both in liquid or solid
form.
RZ 6 with separator and
oil mist filter
... INSIDE THE PUMP
Full-flow oil filter (HF)
Contamination reduces oil and pump life
and increases maintenance cost. This
micro filter efficiently separates micro
particles and polar substances.
A service indicator shows actual filter
conditions and helps to avoid unnecessary filter changes.
Special oils
The performance of oil-sealed rotary-vane pumps is very
much dependent on fluid properties. Some gases or
vapours will either react with the standard pump oil, or
deteriorate its lubrication properties. Both may lead to
problems. For prevention, special oils or fluids may be
used. However, this will require previous conditioning of
the pump by the manufacturer.
WHEN USING OIL-SEALED ROTARY-VANE VACUUM PUMPS
7
GOLDEN
RULES
Warm up pump with inlet closed
Avoid particulates
Never block the outlet
Use gas ballast (for condensable substances)
Use inlet cold trap (for quantities of condensable material)
Before switching off, let pump run for a few minutes
with gas ballast open and inlet closed
Check and maintain regularly
21
Oil mist filters (FO)
All oil-sealed pumps
release oil mist at
the outlet, creating
a nuisance or even a
hazard.
VACUUBRAND oil mist filters will
retain approx. 99.99% of oil mist
at ultimate vacuum.

Rotary-vane pumps have a small flange at the
inlet as standard. On the outlet side there is a
hose nozzle (RE 2.5, RZ 2.5, RE 6 and RZ 6) or a
small flange (RE 9–RZ 16).

SEPARATORS
INLET SIDE AK
Separators are used to protect vacuum pumps from particulates and droplets. When pumping
condensable vapours, it is highly recommended to equip the inlet with a separator or, even better,
with a cold trap. This will help to protect both the vacuum pump and the installation. In the event
of pump failure, the separator will prevent the pump oil from flowing back into the evacuated

Exhaust gases from oil-sealed rotary-vane pumps always carry a certain quantity of oil mist. The
amount depends on the operating conditions such as inlet pressure, gas ballast and pump temperature. To prevent the contamination of air – in and outside the laboratory – this oil mist
should be retained as effectively as possible. VACUUBRAND oil mist filters provide an excellent
rate of separation near 100%. These filters can also be useful in separating other aerosols.

COLD TRAP SKF and GKF
INLINE OIL FILTER HF
Cold traps are used to recover volatile substances – e.g. from distillation – or to protect the pump
against aggressive or otherwise detrimental substances, e.g. solvents or water. Cold traps can also
protect the vacuum system from back-migrating oil vapours. Thus, cold traps protect both the
vacuum system and the pump. They extend maintenance intervals and improve the overall
performance of the vacuum installation.
Particle contamination reduces oil life and increases maintenance needs. The full-flow inline filter
effectively separates micro particles and polar substances. The service indicator shows actual
filter conditions and helps to avoid unnecessary filter changes.

DIAPHRAGM PUMPS
Diaphragm pumps are totally oil-free mechanical vacuum pumps. They do not
use any water and don’t generate waste water nor waste oil. There is no need
for regular oil changes; therefore they offer easy handling. Diaphragm pumps
can be used for a wide range of vacuum applications or for the transfer of
gases in chemistry and physics laboratories.

USE OF DIAPHRAGM PUMPS
PUMPING SPEED: DIAPHRAGM PUMPS
Diaphragm pumps typically offer the best possible vacuum technology in the vacuum range
from atmospheric pressure down to 0.3 mbar
within the laboratory and as backing pumps for
modern wide-range turbo pumps. For use with
chemicals, the gas-contacting parts are made of
corrosion-resistant materials (chemistry diaphragm pump). No waste oil or waste water will
be generated. There is no need for oil changes,
and thus they offer ease of handling compared to
oil-sealed rotary-vane pumps. VACUUBRAND
diaphragm pumps are available for an ultimate
vacuum from < 80 mbar to 0.3 mbar and pumping
speeds from approx. 1 to 12 m3/h, depending on
configuration.
Specifications of ultimate vacuum always refer to
pumps at operating temperature.

DIAPHRAGM PUMPS
There are two basic types of diaphragm pumps: “Aluminium” and
“Chemistry”. The choice depends on the application. For “clean” applications, “Aluminium” gives the best performance. For use with chemicals,
“Chemistry” diaphragm pumps are recommended. The gas-contacting parts
of these pumps are made of corrosion-resistant materials. Typically,
chemistry diaphragm pumps can be used for a wide range of applications in
chemistry laboratories requiring the pumping or transfer of chemically active
gases, e.g. rotary evaporation, vacuum ovens, concentrators and gel drying.

The one-stage diaphragm pumps ME 2 and ME 2C are totally oil-free mechanical vacuum pumps.
The precise geometry of pumping chamber and head space provides a low ultimate vacuum around
80 mbar and a high pumping speed of approx. 2 m³/h. Optimised kinetics for minimum wear of
the diaphragm result in high reliability, low scuffing, long life and low noise level. In a wide range
of applications, they are the modern alternative to water jet pumps for evacuation, and for the
pumping of gases in chemistry and physics laboratories.

Regulator valves for compression and vacuum
The regulator valve for compression allows the adjustment of the outlet pressure. The vacuum
regulator valve allows control of the vacuum level.
These regulator valves can be used in connection with all “Aluminium” VACUUBRAND diaphragm
pumps (but not with “Chemistry”).
Regulator valve for compression
Regulator valve for vacuum
Important information for use of regulator valves for vacuum and compression:
When using the regulator valve for vacuum, it must be ensured that the intake of bleed air will at no time result in the
formation of reactive, explosive or dangerous mixtures. Danger of serious injury or danger to life and a risk of damage to the
equipment and/or the environment may result from the formation of dangerous and/or explosive mixtures, or as result of a
reaction between the air and pumped substances inside the pump or at the outlet.
When using the regulator valve for pressure, it must be ensured that the maximum permissible outlet pressure of the pump
is never exceeded, and that the connected equipment is sufficiently pressure-resistant.

Fully automatic adaptation of vacuum
to actual process parameters (distillation, drying, backing vacuum, etc.)
Environmentally friendly and economical
optimal solvent recovery is maintained by automatic adaptation

USE OF VARIO DIAPHRAGM PUMPS
VARIO diaphragm pumps are the modern finevacuum pumps with adaptive pumping speed,
short pump-down time (at increased rpm) and
long lifetime by reducing the average number of
diaphragm strokes. The lower ultimate vacuum
can result, when used as a backing pump for a
turbomolecular pump, in lower power consumption, and longer lifetime of the wide-range
turbomolecular pump.

VARIO diaphragm pumps provide vacuum control by adaptive motor speed control. They are
modern fine-vacuum pumps with adaptive pumping speed and approx. 20% higher performance
for shorter pump-down times (at increased rpm) and longer lifetime due to a reduction of the
average number of diaphragm strokes. The improved ultimate vacuum leads to lower power
consumption and longer lifetime of wide-range turbomolecular pumps.
VARIO diaphragm pumps always consist of a vacuum pump combined with
a vacuum controller with separate vacuum gauge head.

VARIO diaphragm pumps provide vacuum control by adaptive motor speed control They are
especially recommended for chemical processes that require precise vacuum control. Silent
operation and long lifetime of service parts are achieved through reduced motor speed at working
vacuum level and thus reducing the number of diaphragm strokes. For best overall results with
applications involving significant amounts of condensate, we recommend the VARIO chemistry
pumping units (PC 2001 VARIO, PC 2002 VARIO, PC 2003 VARIO, PC 2004 VARIO, PC 2010 VARIO
or PC 2012 VARIO) with integrated separator and exhaust waste vapour condenser.
VARIO diaphragm pumps always consist of a vacuum pump combined with
a vacuum controller with separate vacuum gauge head.
For detailed information on the Vacuum Controller CVC 2000 II see page 129.

VARIO-SP
DIAPHRAGM PUMPS
VARIO-SP diaphragm vacuum pumps combine extremely small dimensions
with highest performance by an electronically controlled variable-speed
24 V DC motor. They provide compact size, low weight and very low noise
level. The electronically controlled direct-drive motor is maintenance-free
and allows control of the pumping speed over a wide range: increased speed
for fast evacuation; reduced speed for maintaining the vacuum with reduced
power consumption, minimal vibration and noise.

designed as system pumps (SP = SystemPump)
for integration into systems, e.g. leak detectors,
gas analysers, regeneration of cryo pumps, as
backing pumps for wide-range turbomolecular
pumping units, etc. The brushless 24 V DC motor
has extremely compact dimensions and allows
worldwide operation, independent of mains
voltages. The motor speed is electronically
controlled. Materials used like aluminium, FPM,
respectively fluoroplastics (FFKM, PTFE) for the
chemistry design, establish a wide range of applications for vacuum generation.

Due to its variable-speed drive, the three-stage VARIO-SP diaphragm pump MD 1 VARIO-SP attains
considerably higher pumping speeds and a lower ultimate vacuum compared to the corresponding
fixed-speed pump. Compact design and variable mounting positions make the VARIO-SP an ideal
integration and system pump. Its brushless 24 V DC motor makes it applicable to any mains
voltage. For elevated requirements regarding chemical resistance of pump components, the MD 1C
VARIO-SP is available in Chemistry (C) design.

The MZ 2 VARIO-SP diaphragm pump is based on the well-proven design of the MZ 2. The use of
the brushless 24 V DC motor reduces weight and total length of the pump by approx. 40% and
results in an increase of the maximum pumping speed. Therefore, the MZ 2 VARIO-SP is particularly
performant as a built-in pump as part of an instrument. Its 24 V DC motor makes it universal
as regards mains voltage.

CHEMISTRY DIAPHRAGM PUMPS
AND VACUUM SYSTEMS
VACUUBRAND offers chemistry diaphragm pumps and vacuum systems of
equipment category 2 (e.g. for zone 1) with ATEX conformity (European
Union Directive 94/9/EEC). Chemistry diaphragm pumps offer an excellent
basis for avoiding ignition sources due to their high chemical resistance, the
absence of gliding surfaces, and the hermetic sealing of the pumping
chamber. Chemistry vacuum systems with solvent recovery are well proven
configurations for saving time and labour, and protecting the environment.

with potentially explosive atmospheres.
VACUUBRAND chemistry diaphragm pumps and
chemistry vacuum systems with ATEX conformity
are designed to meet these special requirements.
In addition, VACUUBRAND offers a range of ATEX
vacuum gauges with high corrosion resistance
and excellent long-term stability (see pages
125-126).

Even though the appropriate selection
of pump type is most important for an
optimal application, only the addition
of accessories will help to optimise
process performance, economical and
environmental aspects. For best results
it often makes sense to use a reliable
and proven configuration, i.e. a complete vacuum system or pumping unit.
This ensures an optimal fit of the
accessories.

The Chemistry Pumping Units PC 510 and PC 511 are well-proven units for vacuum generation and
controlling of many processes in chemistry laboratories. Due to their two-stage chemistry
diaphragm pump, they are frequently used for medium-sized vacuum applications, e.g. involving
“common” solvents. The PC 510 has an electronically controlled vacuum port. The PC 511 has, in
addition, a manually controlled vacuum port and non-return valves against cross-contamination
and interference, permitting the simultaneous operation of two vacuum systems.
SPECIAL ADVANTAGES
Chemistry diaphragm pump, materials of high chemical resistance
Oil-free vacuum down to 9 mbar (6.8 Torr)
Electronic vacuum controller for effective vacuum control
Solenoid valve (24 V =)
Insulated exhaust vapour condenser, removing vapours condensing under atmospheric pressure at cooling water temperature

SPECIAL FEATURES OF VACUUBRAND HIGH-VACUUM PUMPING UNITS
Efficient
The backing pump generates the necessary backing pressure so that the diffusion pump can always
attain its full pumping capacity of 22 l/s (37 l/s resp.) and ultimate vacuum of approx. 10-6 mbar*
(with pump fluid DC 704 and cold trap).
Rapid
The pumping units have a high-vacuum butterfly valve on top of the diffusion pump, bypass line
and valves. The valves are lever-operated, clearly indicating open/close position. This makes them
particularly efficient for rapid evacuation cycles where the oil diffusion pump stays heated and
ready for operation.
Functional and easy to operate
Smaller experimental set-ups can be mounted directly on the high-vacuum pumping units.
Switches for backing and diffusion pump are centrally grouped on a panel. A short operation
diagram makes the units easy to use. All valves and switches are operated from the front. The
pumping units are vacuum-tight after switching off (with gas ballast valve closed).
Compact and sturdy
Pumps, valves and tubing are compactly mounted on a pillar stand. Due to its small overall dimensions, light weight and air cooling, the pumping unit can be easily transported to the systems to
be evacuated, and can be accommodated almost everywhere. Due to their air-cooled space-saving
design, the high-vacuum pumping units are often used as table-top on laboratory benches.
* Measured with nitrogen cold trap
and cold-cathode ionisation
vacuum gauge, directly at the
high-vacuum valve
Economical
The High-Vacuum Pumping Units HP 40 B2 and HP 63 B2 have a power consumption of only
0.4 kW and 0.54 kW and do not require any water supply. They are very economical compared to
wide-range turbomolecular pumps, since there is no costly regular maintenance (e.g. replacement
of rotor bearings).

The combination of an oil-free chemistry diaphragm pump with a Roots pump leads to an increase
in pumping speed and results in a lower ultimate vacuum by an order of a magnitude.
VACUUBRAND Roots Pumping Units RP feature a high specific corrosion resistance. Their good
pumping speed, particularly in the pressure range between 0.2 and 50 mbar, allows the pumping
of large amounts of vapours. Roots pumping units are used for many vacuum applications in
chemistry (e.g. distillation, drying, etc.) and especially for many demanding “oil-free” applications, such as load lock systems, electron microscopes and mass spectrometers, or as oil-free
backing pumps for turbomolecular pumps and cryo pumps.

Options for aspiration
91 FLUID ASPIRATION SYSTEM: BIOCHEM VACUUCENTER BVC
The BioChem-VacuuCenter BVC is designed for professional fluid aspiration in chemistry, biochemistry, biology and medicine, e.g. of fluid supernatants from microtitre plates, petri dishes,
cell culture bottles, etc. The handle will accommodate pipettes and tips of various sizes. The BVC
offers automatic vacuum control and an autoclavable 4-litre collection bottle with self-closing
quick-fit couplings. The aspiration speed is controlled by the VacuuHandControl VHC handset.
A thumb-operated peristaltic pump allows the removal of minute quantities of excess liquid,
without interfering with sediments. The automatic vacuum control switches the pump on/off
according to demand (no need for a foot switch). The option of adding a second VHC handset
makes the BVC 21 a low-cost aspiration system for two independent workstations. The model
BVC 01 (collection bottle and vacuum switch, without pump) is designed for use with a
VACUU·LAN® local-area vacuum network or other existing vacuum supply.

On the inlet side:
Inlet separator
Solvents and particles will reduce the lifetime of diaphragms and
valves. Separators effectively protect the pump and can extend
lifetime considerably.
Solvent recovery has become an important factor for vacuum generation in the chemistry laboratory. An insulated exhaust vapour
condenser at the outlet allows solvent recovery rates next to 100%
without the need for elaborate refrigeration systems. The AK + EK
combination provides protection to the pump both at the inlet and
outlet and, in addition, an efficient solvent recovery system.
CONTROLLER SUPPORT WITH IEC SOCKET
With the Controller Support, the Vacuum Controller CVC 2II can be
mounted directly on the base plate (pump support). The Controller
Support also allows to group the electrical supply. A single switch
turns both the Vacuum Controller and the vacuum pump on and off.
Power cables of any national type can be connected through the
IEC socket.

On the outlet side:
Outlet separator
Condensables can be trapped by a catchpot at the outlet side. This
facilitates controlled waste disposal or recycling. The outlet
separator can also prevent condensates from returning from the
outlet into the pumping chamber, which otherwise might reduce
the lifetime of the valves in particular.

USE OF VARIO CHEMISTRY PUMPING UNITS
VACUUBRAND VARIO Chemistry Pumping Units
provide vacuum control by precise adaptation of
diaphragm pump motor speed. They automatically identify the vapour pressures and continuously adapt the vacuum to parameter changes.
Quick and precise adaptive control adjusts
pumping speed to actual process requirements,
irrespective of apparatus size and volume of
vapours. An ultimate vacuum down to 0.6 mbar
can be attained. Process times are shortened by
high evaporation rates through continuous
evaporation. Solvent recovery next to 100% is
supported through continuous evaporation. The
on-demand motor speed control significantly
reduces the overall workload of the diaphragm
pump, resulting in unmatched values for total
lifetime of service parts.

VACUUM VALVES
VACUUBRAND offers the following lines of vacuum
valves:
Ball valves The simplest type of isolation devices are
ball valves. They are made of brass (VK) or stainless
steel (VKE). In the open position, they offer a totally
free cross section with high conductance and are particularly useful e.g. for load locks. Typical applications
are the rough and fine vacuum range.
Diaphragm valves VACUUBRAND VM diaphragm valves
are manually-operated inline valves. They are designed
for applications involving corrosive gases and vapours.
Their PTFE diaphragm and stainless steel body offer
excellent corrosion resistance.
High-vacuum bellow valves The VE AL right-angle
valves are bellow-sealed and have an aluminium body.
They are operated by a screw-thread mechanism and
combine exceptional leak tightness with some control
characteristics.
Right-angle valves The VACUUBRAND VE TIG valves
– bellow-sealed right angle valves made of stainless
steel with TIG welded flanges – fulfil high requirements as regards leakage rate, gas emission, corrosion
and temperature resistance and bakeability.
Butterfly valves VACUUBRAND butterfly valves of the
VS series are inline valves with high conductance. They
require little space, provide clear visual indication of
valve open, have a low leakage rate, low mass and low
cost.
Two components are connected via a seal ring
and a centring ring, keeping both the seal and
components in position. A clamping ring is used
for fixing and for applying mechanical force to
the gasket. Various types of gaskets allow to
choose the most suitable and economical solution for any application.
Clamping rings Aluminium clamping rings with
wing nuts, for use with soft rubber-elastic or
indium metal gaskets. The barrel burnished bright
metallic surface is reasonably corrosion-resistant.
Centring rings Stainless steel centring rings are
internal centring rings complying with
DIN 28 403 (ISO KF).
TRAPPED O-RING CENTRING RINGS
Trapped O-ring centring rings have been developed
in order to avoid a number of disadvantages of
standard internal centring rings. An outer ring
guides the seal on the outer diameter of the small
flange, the gasket is retained inside. Thus one
external centring ring replaces 3 different standard
internal centring rings. Additionally, a particular
advantage is that there are no crevices on the
vacuum side to trap gas, which could generate gas
bursts and/or slow down pumping.
GASKETS
NBR is a low-cost sealing material, widely used
in high-vacuum technology. It is resistant to oil
and can be used in the temperature range from
approx. –25 °C to approx. +80 °C.
FPM has approximately half the degassing rate of
NBR. It can be used in the temperature range
from approx. –40 °C to approx. +150 °C and thus
also can be used for bakeable flanges in highvacuum technology.
Indium gasket rings Indium gaskets combine
the advantages of an all-metal gasket with the
easy handling of a standard elastomer smallflange coupling. They avoid elastomer disadvantages like degassing and damage through radiation, and can be used with the normal aluminium
clamping ring with wing nut. Handled carefully,
they remain leak-tight even after repeated use
(approx. 20 times). Limited bakeability.
Aluminium gasket rings Aluminium gaskets
have a higher temperature range – up to approx.
+200 °C. We recommend the use of stainless
steel small-flange components.
Filter centring rings Filter centring rings are stainless-steel, common
internal centring rings with press-fitted sintered non-ferrous metal
discs and an NBR gasket. Filter centring rings can be used replacing
common centring rings to protect pipe systems, plant parts, pumps
etc. from particles.
VACUUBRAND SMALL-FLANGE COMPONENTS (ISO KF)
The comprehensive range of small-flange components (ISO KF) includes almost all types in practical use such as nozzles, flange weld
stubs, reducing pieces, elbows, T-pieces, cross pieces, reducing cross
pieces and blanking flanges.
Special advantages: sealing area provides proper surface for maximum
gas-tightness when using elastomer seals. In most cases, sealing surfaces come protected by plastic caps which, when reused, also provide protection during storage. The program offers aluminium and
stainless steel fittings.
Aluminium components Aluminium components are characterised in
particular by their low mass and are therefore especially used for selfsupporting systems down to about 10-6 mbar.
Stainless steel These components are used whenever corrosion
resistance, low outgassing and/or clean conditions are essential. Components made of 1.4541 steel are for use where acid vapours are
present; otherwise, 1.4305 steel is used. Special feature of
VACUUBRAND parts: TIG welded and almost all welds made from the
inside even in NW 10 components (leakage < 10-9 mbar x l/s).
FLEXIBLE CONNECTIONS
With flexible connections, axial offsets or misalignments of system
components can easily be compensated.
Rubber Internal rubber tubes are thick-walled, intrinsically stable
tubes of nominal diameters from 6 to 20 mm, flexible and tight-fitting
when connected to hose nipples.
PVC PVC tubes are most common for the larger nominal diameters (20,
28, 45). They are reasonably chemically resistant, but need a steel
reinforcing spiral. Due to their transparency, they are also used for
checking the formation of condensates (to 1 mbar).
PTFE antistatic Vacuum tubing of antistatic PTFE with small flanges
of stainless steel. Almost even inside walls for high conductance and
against condensate accumulation. Material with excellent chemical
resistance and antistatic properties (resistance <10 7 Ohm between
inside and flanges) to prevent electrostatic build-up. Helium leaktested.
Stainless steel Stainless steel metal bellows and hoses, as flexible
connections, satisfy high standards regarding gas emission (outgassing) and cleanliness. Parallel corrugated metal hoses are made of
1.4541 steel. The flanges – also stainless steel – are TIG-welded and
helium leak-tested.
SMALL-FLANGE FITTINGS
Vacuum systems with small-flange components often require adaptors
for connection to other components such as glass tubing, ground
joints etc.

BALL VALVES
VK
Ball valves
VK
..........
brass
VKE . stainless steel
VACUUBRAND ball valves of the VK series with small flanges are low-cost, sturdy isolation devices
for the rough and fine vacuum range. A precisely machined ball with a hole through the middle is
rotated by means of a shaft and lever. When the valve is open, the hole provides unimpeded passage of media over the entire nominal cross section. Ball valves are therefore also used for load
locks, e.g. for sample holders, thermocouples or helium supply lines. When closing the valve, residual gas will be trapped in the hole and may be released into the system when the valve is opened
again. VACUUBRAND ball valves are available with brass body, chrome plated brass ball and adhesive bonded small flanges (VK). The VKE series use stainless steel for the metal parts with TIGwelded flanges and glass-fibre reinforced PTFE seatings. This design offers a high degree of corrosion resistance and bakeout capability.

BUTTERFLY VALVES
VS
The VS, VS C, and VS B series valves are butterfly-type valves. A circular valve plate with a sealing
ring on the circumference rotates around an axis at right angle to the valve axis. As a result, the
valves leave virtually the entire cross section free, offering very good conductance. The valve bodies
are made of one piece, machined from solid material, and require (in addition to the valve head seal)
only one elastic shaft seal for rotational movement of the shaft. An economic solution that provides
low leakage and minimal degassing rates.
SPECIAL ADVANTAGES
Compact, economic design
High conductance, low leakage rate
Gas-tight against atmosphere in both positions
No trapped gases
Easy to grip, lever-operated, with position
indicator

GAS INLET VALVES
VG
VACUUBRAND gas inlet valves VG are small hand-operated valves for admitting gases into a
vacuum system. By rotating a knurled screw cap, the valve stem is raised from the valve seat.
Thus, gas enters at a controlled flow rate from the line connected to the gas inlet. The gas inlet
valve VGS 10 is small-flange mounted to the system and has a hose nipple NW 8 for connection
to gas cylinders, air driers, or for admitting air directly. The vacuum and atmospheric sides of the
gas dosing valve VGL are provided with hard-soldered brass connections, facilitating the valve to
be used as a fixed, permanent fitting.

VACUUBRAND valves of the VV series are solenoid-operated spring-return inline valves with FPM
diaphragms. These valves are designed for a large number of operations at short intervals and are
therefore often used as flow-control valves. The straightforward design results in a low-cost valve
with low leakage rate. The VV C series valves are made of materials with higher chemical
resistance. The seal is made of an elastic fluoroelastomer with excellent chemical resistance and
significantly better long-term tightness properties compared to PTFE.

VACUUM GAUGES
AND CONTROLLERS
The VACUUBRAND line of vacuum gauges offers electronic gauges and
controllers in the range from 1000 to 10 -3 mbar. Instruments can be
calibrated and certified according to the German Calibration Service (DKD)
under the supervision of the German Federal Standards Laboratory (PTB).

MEASURING PRINCIPLES
DIAPHRAGM VACUUM GAUGES
Vacuum used in scientific and technical applications ranges from atmospheric pressure
(approx. 1000 mbar or 750 Torr) down to approx.
10-11 mbar. Below 1 mbar, pressure is usually
determined indirectly. Properties which depend
on the density of gas are used, e.g. thermal
conductivity. However, indirect measurement
principles that measure a pressure-dependent
parameter depend on the composition of the gas.
Modern electronic diaphragm vacuum gauges
have capacitive or piezo-resistive pressure
transducers. The bending of the diaphragm is
converted into an electrical signal. Gas pressure
(force per area) is measured directly. Therefore,
these instruments will work independently of gas
composition.
The measuring principle used determines the
measuring range, the accuracy and the dependence of results from gas composition and other
parameters.
VACUUBRAND offers electronic gauges and
controllers covering the range from atmospheric
pressure down to about 10-3 mbar/Torr. Thus,
the user can choose the instrument that is
technically and economically most appropriate
for a specific application. Instruments can be
calibrated and certified by VACUUBRAND
according to the government-authorised German
Calibration Service (DKD).
The signal is processed electronically, and a readout is provided on a large LCD display in digital
and analogue format.
Capacitive pressure transducers are generally
more accurate and can be made of chemically
more resistant materials. VACUUBRAND uses
gauge heads with chemically resistant aluminaceramic diaphragms for use in the chemical
laboratory. These gauges are easy to use, offer
high accuracy, long-term stability, and can easily
be recalibrated.
In the vacuum range from 10 to 10-3 mbar
indirect measuring instruments, often based on
thermal conductivity, have become very common.
Pirani vacuum gauges use the thermal conductivity of gas, which is dependent on density and
hence on pressure. This gas property varies
significantly only in the range from 100 to
10-2 mbar. Therefore, these instruments offer
reasonable precision and good resolution only
within this range. From atmospheric pressure to
approx. 100 mbar, and again below 10-2 mbar,
even large changes of pressure only result in a
small change of signal. In these marginal areas,
only trends can be detected, and even specific
readouts must not be interpreted as precise
measurements.
Pirani-type gauges indicate total pressure. However, the reading is dependent on the type of gas.
For residual gases with good thermal conductivity, such as helium and hydrogen, the true
vacuum value is lower than the indicated value.
Vice versa, when gases with poor thermal conductivity dominate, such as argon, neon and
carbondioxide, the true pressure will be higher
than the value shown on the display. At
VACUUBRAND, all gauges are calibrated for air.
“EX” VACUUM GAUGES
The fully electronic vacuum gauges DVR 3
and DVR 4 have ATEX certification for use
in areas with potentially explosive atmospheres
as per ATEX category 2 (e.g. for measurement in
zone 1, DVR 3) and/or per ATEX category 1 (e.g.
MODEL
for measurement at zone O, DVR 4/4S). These compact instruments are
highly versatile and provide vacuum measurement in the range from
atmospheric pressure down to 1 mbar. The devices are characterised by
high overload tolerances, high permissible gas temperatures, and
optional splash-protected versions for demanding operating conditions. These capacitive vacuum gauges are battery-operated and
therefore do not require an external power supply, which is a particular advantage when operating within hazardous areas. Features such
as automatic sleep mode and automatic adaptation of sampling rates
result in long operating life. The battery level indicator allows to estimate the remaining operation time.
VACUUM CONTROLLERS
VACUUBRAND vacuum controllers are fully electronic combined
vacuum gauges and control units. The Vacuum Controllers CVC 2II and
VNC 1 provide “classic” two-point control in conjunction with a
solenoid-operated vacuum line valve. The Vacuum Controllers
CVC 2000II and VNC 1 can provide superior single-point vacuum
control by motor speed variation of VARIO diaphragm pumps. This
allows the fully automatic adaptation of vacuum levels to momentary
process demands.
DKD CALIBRATION
The VACUUBRAND DKD Calibration Laboratory offers a calibration and certification service for vacuum gauges in the vacuum range
from 1000 to 10-3 mbar. It is regulated and accredited in accordance
with the government-authorised German Calibration Service (DKD) and
fulfils the international standards for testing laboratories ISO/IEC
17025. Measuring instruments calibrated in the VACUUBRAND DKD
Calibration Laboratory also fulfil the requirements for ISO 9000ff (quality management) and ISO 10012 (control of inspection, measuring and
testing). DKD-calibrated vacuum measuring equipment can be traced
back to the national standards of the German Federal Standards
Laboratory (PTB).

VACUU·CONTROL
VACUU·CONTROL
Programmed control and recording of sequencing vacuum processes
The PC software VACUU· CONTROL allows the control of vacuum processes in research, development, and production. VACUU· CONTROL works in conjunction with the Vacuum Controller
CVC 2000 II (in Vacuum Pumping Units series PC 2001 VARIO to PC 2012 VARIO and VARIO
Diaphragm Pumps MZ 2C, MD 4(C), MV 2 and MV 10 VARIO), the Vacuum Network Controller VNC 1
(also in PC 500 LAN, PC 600 LAN) and the Vacuum Gauge DVR 5 (data recording only).
The software controls the entire vacuum process, automatically documenting the process data,
which can be exported to other programs. Its graphical interface and simple programming make
the VACUU· CONTROL software very user-friendly. It makes it very easy to define a vacuum process
run (e.g. for distillation or drying processes), including ramps, stop points, vacuum levels, or gas
admission points.
The software is installed from the CD-ROM on a Windows® compatible PC, which is connected to
the vacuum controller or gauge via the RS 232C interface. Demo programs are provided to help
the user with the programming of ramps and vacuum cycles, with or without gas admission, and
much more. Measured pressure data are recorded and made available for subsequent analysis, e.g.
in Microsoft Excel®. This facilitates process validation, which is becoming increasingly important
in many areas.

VACUUM EQUIPMENT
VACUUBRAND offers a wide range of vacuum systems for chemistry, physics

regarding technical, economical and environmental aspects. “Choosing
Vacuum Equipment” should help you to select the right product according to
your specific application.
CHOOSING VACUUM EQUIPMENT –
THE RIGHT CHOICE FOR
YOUR APPLICATION
Chemistry Pumping Unit PC 2001 VARIO
Rotary-Vane Pump RZ 6
134 CHOOSING VACUUM EQUIPMENT
THREE STEPS TO CHOOSE YOUR EQUIPMENT
Step 1: Decide which range of vacuum you want
to work in
Step 2: Determine the gas load (required
pumping speed)
Step 3: Additional requirements, like oil-free
vacuum, chemical resistance, solvent recovery,
vacuum control, etc.
DIAPHRAGM PUMPS
(down to approx. 1 mbar)
Diaphragm pumps are totally oil-free, do not consume
water and do not produce any waste water. They are
often the best choice for noncorrosive applications, e.g.
as backing pumps for turbomolecular pumps, for the
regeneration of cryo pumps, and for contamination-free
evacuation and transfer of gases.
CHEMISTRY DIAPHRAGM PUMPS
(down to approx. 1 mbar)
In modern chemistry diaphragm pumps, all wetted parts
are made of fluoroplastics of high chemical resistance.
They do not need any elaborate cold traps and allow the
Chemistry Vacuum Pumping Unit PC 8 / MV 10C
thermodynamically much more efficient condensation at
the outlet. This facilitates improved solvent recovery
near 100%. Modern chemistry diaphragm pumps are part
of a modular system, which provides the option of upgrading or retrofitting the pump up to a complete pumping
unit with vacuum control and solvent recovery system.
VACUUM PUMPING UNITS
(down to approx. 10-6 mbar)
Vacuum pumping units offer the advantage of being
supplied ready-for-operation, and an optimal configuration of accessories. They are available for rough, fine
and high-vacuum applications. For each vacuum range,
the appropriate vacuum pumps are at the centre of the
pumping unit: chemistry diaphragm pumps for rough
vacuum (down to 1 mbar); combinations of chemistry
diaphragm pumps and Roots pumping units for fine
vacuum (down to 10-1 mbar); oil-sealed rotary-vane
pumps for fine vacuum (down to 10-3 mbar); oil diffusion pumps for high vacuum (down to 10-6 mbar). Many
pumping units have an integrated vacuum controller for
simple operation and better vacuum control.
When rotary-vane pumps are used for the pumping of chemicals, they should be protected with
appropriate accessories like cold trap, separator,
etc. Of particular importance is the wide range of
useful accessories and the maintenance-friendly
design. Generally, rotary-vane pumps should be
allowed to warm up with closed inlet for approx.
15-30 min. After operation, they should run for
another 15 minutes with closed inlet and with
gas ballast. An isolation valve with good corrosion resistance may be required.

CHEMISTRY HYBRID PUMP RC 6
(below approx. 5 mbar)
mbar 10-6
10-5
(below approx. 5 mbar)
For low pressure ranges (below approx. 5 mbar), the Chemistry Hybrid
Pump RC 6 is the real chemistry pump. The oil-sealed part of a special
rotary-vane pump is permanently evacuated by a chemistry diaphragm
pump. Condensation, corrosion and contamination of the oil are significantly reduced. In most cases, no expensive cold trap is required
to protect the pump. Evacuated gases can easily be collected at the
pump outlet with high thermodynamic efficiency. Solvent recovery
close to 100% is possible, and the amount of waste oil is reduced
drastically.

CHOOSING VACUUM EQUIPMENT
– for Filtration and Aspiration
136 CHOOSING VACUUM EQUIPMENT – FOR FILTRATION AND ASPIRATION
Filtration can be accelerated by pressure above the filter and/or with the aid of vacuum below
the filter. The requirements on the vacuum supply (control and ultimate vacuum) are usually
limited. When filtration is processed at 80 mbar, 92% of atmospheric pressure are already
available as a driving force for filtration. Lowering the vacuum further would not significantly
increase the filtration speed. For these reasons, one or two-stage diaphragm pumps are sufficient
for most filtrations. Depending on the size and leak rate of the system, the pumping speed of the
vacuum pump is an important parameter. Depending on the solvents used, a chemistry diaphragm
pump may be required. Upgrade kits that contain a separator (AK) and an exhaust waste vapour
condenser (EK) protect the pump against droplets and minimise the impact of solvent vapours on
the air in the lab and the environment. Complete chemistry pumping units with vacuum
controllers allow automatic filtration.

Depending on gas volume and selected pump, one single pump can simultaneously operate
several filtration and/or other vacuum applications (see pages 118-121).
CHOOSING VACUUM EQUIPMENT
– for Gel Dryers
Gel dryers put elevated demands on the vacuum system. Beside good chemical resistance, a high
tolerance to condensates will be needed. The required ultimate vacuum depends on the gels used
and the degree of dryness required (in some cases, as low as 10 -1 mbar). In most cases, however,
two or three-stage diaphragm pumps with 9 or 2 mbar, respectively, are sufficient. Since high leak
rates can be expected during drying processes, a pump with sufficient pumping speed at the
respective working vacuum level should be selected. Pumping units with separator (AK) and
exhaust waste vapour condenser (EK) are advisable. Vacuum control is advantageous.
Requirements:
Chemical resistance
Tolerance to condensates
Vacuum performance independent from external parameters
Ultimate vacuum 2 mbar
Vacuum for gels, commonly dried by water-jet vacuum,
e.g. sequence gels, SDS-PAGE up to 10%

CHOOSING VACUUM EQUIPMENT
– for Drying Chambers
Vacuum drying chambers are used for sensitive substances and in applications where full drying
from residues has to be achieved. Depending on the degree of dryness, the maximum permissible
temperature and the solvents involved, a very low ultimate vacuum may be needed. During certain drying processes, large amounts of vapour may occur, which can only be handled by pumping
systems with high pumping speeds. A good tolerance to condensates is an important requirement
for pumps used with drying chambers. Gas ballast, which comes as standard with VACUUBRAND
Chemistry Diaphragm Pumps, is a useful feature in this regard.
Requirements:
High pumping speed and low ultimate vacuum
High water vapour tolerance
Good chemical resistance
Tolerance to condensates
The right choice:

– for Rotary Evaporators
Vacuum requirements for rotary evaporators can vary considerably. Important features are
chemical resistance of the pump system, high tolerance to condensates and, particularly, the
ultimate vacuum and, last but not least, high accuracy of vacuum control. For this type of
application, pumping units are extremely advantageous. For very basic processes, pumping units
with manual vacuum control may be sufficient. Pumping units with electronic 2-point valve
control will often provide acceptable results. The best available control features are offered by
VARIO Chemistry Pumping Units: vacuum control with pinpoint precision, and fully automatic
boiling point recognition and tracking – all combined with unsurpassed user-friendliness.
VARIO = The right vacuum at the push of a button:
Find vacuum level, follow vapour pressure, control with precision, all automatically!
The right choice:
Ultimate vacuum 9 mbar
For low-boiling-point solvents, e.g. solvents which
formerly could be evaporated by “water-jet vacuum”,
e.g. H2 O at 20 °C bath temperature

– for Concentrators
Vacuum concentration puts high demands on a vacuum system regarding condensate tolerance
and, in some instances, ultimate vacuum. If high-boiling-point solvents such as DMF or DMSO are
evaporated at low temperatures and/or to a low degree of residues, an ultimate vacuum down to
10 -3 mbar may be necessary. Appropriate vacuum sources include four-stage chemistry diaphragm
pumps and pumping units, Roots pumping units, or the Chemistry Hybrid Pump RC 6, possibly with
the addition of a cold trap.

CHOOSING VACUUM EQUIPMENT
Freeze drying requires an ultimate vacuum between 10-1 and 10-3 mbar. Vacuum systems should
have elevated chemical resistance and condensate tolerance. For freeze drying, VACUUBRAND
offers Roots Pumping Units RP, two-stage rotary-vane pumps (RZ 2.5 - RZ 16) and the Chemistry
Hybrid Pump RC 6. Due to the special design of the Chemistry Hybrid Pump RC 6 (combination of
a rotary-vane and a chemistry diaphragm pump) often the use of an additional cold trap will not
be necessary. Its significantly increased condensate tolerance and therefore extended lifetime, as
well as its extended oil change intervals will very quickly offset the higher purchase cost of the
RC 6, compared to a conventional rotary-vane pump.
Molecular distillation processes require a vacuum range from 10-3 to 10-6 mbar. The High-Vacuum
Pumping Units HP for this level of vacuum are completely assembled rotary-vane/diffusion pump
combinations with all connections and valves.
Requirements:
Low ultimate vacuum, even with gas ballast
Chemical resistance
Tolerance to condensates
The right choice:
Ultimate vacuum 10-1 mbar For freeze drying down to –20 °C, even without chiller,

VACUU·LAN® Network
The Local-Area Vacuum Network VACUU·LAN® makes it possible to supply several different
applications in the laboratory with one single vacuum pump or pumping unit. The connecting
parts are modular and very versatile and can be assembled or modified without any tools. The
modules have integrated non-return valves with high effectiveness against interference or crosscontamination, even at low pressure differences.
3 steps to the appropriate VACUU·LAN® Local-Area Vacuum Network:
Step 1: What application?
Look for your application on the chart on the opposite page.
Determine the required ultimate vacuum and pumping speed (also consult the preceding pages).
On the chart, proceed from the top downwards.
Step 2: Which vacuum port?
142 CHOOSING VACUUM EQUIPMENT – VACUU·LAN®
Which types of VACUU·LAN® modules are apropriate for your application
Selection criteria could be:
Shut-off valve
Flow control
Automatic vacuum control
Size of the application (for very small applications, a flow control is recommended)
Which type of connection?
The main criterion is whether the VACUU·LAN® network will be installed into existing furniture, or
whether it is planned for a new laboratory (see page 120 for description of connecting elements).
Location (e. g. hood)
Lab furniture manufacturer
The appropriate Cat. No. results from of the combination of VACUU·LAN® module and connecting part
(see page 121).
Step 3: Which vacuum pump / pumping unit?
Generally, an inlet separator (AK) and an exhaust waste vapour condenser (EK) are advisable.
Additional criteria:
1. Operating vacuum
Two-stage (9 mbar ultimate vacuum) or three-stage (2 mbar ultimate vacuum) vacuum pumping
units (MZ or MD).
Note: When the operating vacuum approaches the ultimate vacuum of a two-stage pump, then a
three-stage pump is advisable, because a two-stage pump provides only limited pumping speed
around 10 mbar.
2. Size of vacuum network, number of vacuum ports:
The wider the VACUU·LAN® network, and the more vacuum ports being used simultaneously, the
higher the pumping speed of the pump must be.

3. Pump and cooling water management:
Control of vacuum supply and cooling water should be planned according to requirements.
Automatic stand-by periods (sleep modes) minimise waste of energy and cooling water.

7 Warranty, damages, supply of spare parts
7.1 VACUUBRAND is liable only that products including installation is free of defects
at the transfer of risk. Qualities, properties, performance or other features shall
be binding only if VACUUBRAND has expressly warranted them in writing to the
customer. Details in advertisements and instructions for use, or reference to
industrial standards shall not constitute warranted qualities or the taking-on of
particular obligations.
7.2 If the customer requires the products for special purposes which exceed the
agreed or anticipated use, he must check before use if the products are suitable
for such purposes – including all aspects pertaining to product safety – and customer is required to ensure that products comply with all relevant technical, legal
and official regulations and requirements. VACUUBRAND shall not be liable for any
damages caused to the customer and/or to his property or any subsequent user if
such proper verification has not been performed by the customer and proper written authorisation was not obtained from VACUUBRAND. If the customer has
expressed special requirements regarding materials of construction or design
modifications, VACUUBRAND is not liable for testing the suitability or approving
the requested material or design and is therefore not responsible for any examination as to suitability, worthiness or appropriateness for any particular application.
7.3 VACUUBRAND’s liability is limited to deferred fulfilment of the contract. Subject
to VACUUBRAND’s disposal deferred fulfilment will be repair of defaults or supplying a product free from defects. Further claims may only be raised if
VACUUBRAND refuses to perform as stated above or if VACUUBRAND fails to repair
or replace or if it becomes impossible to repair or replace the defective product.
In case the customer has transferred the products after delivery to another place
which results in additional expenses to repair or replace – e.g. freight, travel
expenses, etc. – the customer has to bear the additional costs. In case a product
should prove to be defective as per the a.m. warranty within one year from date
of shipment to the original purchaser, the exclusive remedy of the customer is the
replacement or repair (at VACUUBRAND’s sole discretion) of the defective product.
7.4 If the products delivered are destined for the customer’s business, he shall be
obliged to check incoming products as to quantity delivered and defects and
report claims to VACUUBRAND within one week from delivery. Failure to do so will
void any and all potential claims for warranty for these defects.
7.5 VACUUBRAND is not liable for any damages following improper use or handling.
All wearing parts (e.g. pistons, seals, diaphragms, valves and oil) as well as breakable material like glass and ceramic are excluded from any warranty. Any and all
warranties are null and void if the products have been processed, consumed in
any way, or maintained by the customer or by third parties.
7.6 In case customer is using the product in contact with hazardous, toxic, radioactive, environment damaging or any other dangerous substances, law and regulations will require a decontamination of the product and a safe disposal of the hazardous material usually at the customer’s premises prior to any repair or replacement of the product. Prior to any return shipment, customer shall be obliged to
clean and decontaminate the products and bear the costs for such decontamination.
7.7 VACUUBRAND is liable for any damages other than damages to the product only
on intent or gross negligence. VACUUBRAND will be liable only if the customer has
informed VACUUBRAND before concluding the contract expressly in writing about
the possibility of such damages and if VACUUBRAND has agreed to such additional
obligations in writing. In so far, liability is limited to typically foreseeable damages.
7.8 All claims – except for products which according to their normal use will be used
for a building – will be in lapse within one year after delivery of the product to
the customer. This also applies to all other obligations and/or for compensation
for all damages other than direct damage on the delivered product including property damages.
7.9 The warranty period for any replacement parts provided by VACUUBRAND under
warranty shall lapse at the end of the warranty period for the original product.
8.
Spare parts
VACUUBRAND will generally supply spare parts for a period of five years from the
date of delivery of the original product. If the spare parts are not manufactured
by VACUUBRAND and are no longer available on the market or if the required raw
materials are no longer available, VACUUBRAND’s obligation to supply spare parts
shall lapse.
9. Disposal of Products
9.1 The customer shall bear any costs arising from disposal. If law and regulations
require a special disposal procedure for equipment supplied by VACUUBRAND, e.g.
EU directives such as WEEE directive, RoHS directive), the customer shall be
responsible for making sure that any requirements are fulfiled and shall bear any
costs. If law and regulations require that VACUUBRAND takes a product back for
disposal, the customer shall bear directly any costs arising from the disposal or
shall refund them to VACUUBRAND. VACUUBRAND may only take back the product
on the condition that the customer prepaid the disposal or has given an appropriate security.
10. Industrial proprietary rights, secrecy
10.1 VACUUBRAND reserves ownership in any tools, moulds, samples, diagrams, commercial or technical documents provided by VACUUBRAND as well as all copyrights, proprietary and intellectual property rights in any such item. This applies
also if the customer has partly or wholly borne their costs. The customer may use
all such items only in formats approved by VACUUBRAND in writing, he is neither
entitled to manufacture these items nor to have them manufactured on his
behalf.
10.2 The customer is responsible that the use of drawings, models, samples, or instructions as provided to VACUUBRAND by the customer shall not infringe industrial
property rights or other rights of third parties. The customer shall be liable for
payment of all expenses, awards, damages, and other compensation to outside
parties and all cash and non-cash expenses in defending any allegation of such
infringement.
10.3 All information acquired through the business relationship which is not deemed
