CHAPTER 1
INTRODUCTION
Congratulations on your purchase of a Labconco FreeZone®
Freeze Dry System, which is designed for laboratory lyophilization
procedures. The refrigerant used in the refrigeration system is
CFC-free so it will not endanger the environment. The unit is easy
to install and maintain. Proper care and maintenance of this
product will result in many years of dependable service.
Freeze Dry Process
Freeze drying is an important process in sample preparation and
for the preservation and storage of biologicals, pharmaceuticals
and foods. Of the various methods of dehydration, freeze drying
(lyophilization) is especially suited for substances that are heat
sensitive. Other than food processing (e.g., coffee, whole dinners),
freeze drying has been extensively used in the development of
pharmaceuticals (e.g., antibiotics) and preservation of biologicals
(e.g., proteins, plasma, viruses and cell lines). The nondestructive
nature of this process has been demonstrated by the retention of
viability in freeze dried viruses and microorganisms.
Freeze drying is a process whereby water or other solvent is
removed from frozen material by converting the frozen water
directly into vapor without the intermediate formation of liquid
water. The basis for this sublimation process involves the
absorption of heat by the frozen sample in order to vaporize the
ice; the use of a vacuum pump to enhance the removal of water
vapor from the surface of the sample; the transfer of water vapor to
a collector; and the removal of heat by the collector in order to
condense the water vapor. In essence, the freeze dry process is a
balance between the heat absorbed by the sample to vaporize the

Chapter 1: Introduction
ice and the heat removed from the collector to convert the water
vapor into ice.
Freeze Dry Rates
The efficiency of the freeze drying process is dependent upon the
surface area and the thickness of the sample, the collector
temperature and vacuum obtained, the eutectic point and solute
concentration of the sample. It is important to remember these
factors when trying to obtain efficient utilization of your freeze dry
system. A listing of selected materials and their approximate
drying times are shown in Table 1 for your reference.

*Total sample quantities are contingent on various freeze dryer capacities.
Up to the point of overloading the system, the greater the surface
area of the sample, the faster the rate of freeze drying. By contrast,
for a given surface area, the thicker the sample the slower the rate
of freeze drying. This is based on the fact that the heat of
sublimation is usually absorbed on one side of the frozen sample
and must travel through the frozen layer to vaporize water at the
other surface. In addition, as the sample is freeze dried, the water
vapor must travel through the layer of dried material. The thicker
the sample, the greater the chance that the dried layer may collapse
which would cause an additional decrease in the rate of freeze
drying.
The surface area and thickness of the sample can usually be
ignored when each sample contains only a few milliliters.
However, for larger volumes, the samples should be shell frozen to
maximize the surface area and minimize the thickness of the

Chapter 1: Introduction
sample. The volume of the freeze dry flask should be two to three
times the volume of the sample.
In order for lyophilization to occur, ice must be removed from the
frozen sample via sublimation. This is accomplished by the
collector and the vacuum pump. The collector, which should be at
least 15 to 20°C colder than the eutectic temperature (melting
temperature) of the sample, traps vapor as ice. Since the vapor
pressure at the collector is lower than that of the sample, the flow
of water vapor is from the sample to the collector. Since this vapor
diffusion process occurs very slowly under normal atmospheric
conditions, a good vacuum is essential to maintain an efficient rate.
In many applications, the maintenance of a vacuum of 0.133 mBar
or less is recommended.
The rate of freeze drying is directly proportional to the vapor
pressure and the vapor pressure is dependent upon both eutectic
temperature and solute concentration of the sample. For example,
a solution of sodium chloride and water would freeze dry at a
slower rate than pure water. The eutectic temperature of a sodium
chloride solution is about –21°C and at this temperature the vapor
pressure is about 1/16 that of water at 0°C. Although the eutectic
temperature is not dependent upon the concentration of sodium
chloride, the vapor pressure of the water would decrease as the
concentration of sodium chloride increased. This is due to the fact
that as the solute concentration increases, less of the surface area of
the frozen sample is occupied by water. In general, most solutions
or biological samples will have a eutectic temperature of –10° to
–25°C. However, if the sample contains a simple sugar such as
glucose or if the sample is animal or plant tissue, the eutectic
temperature may be as low as –30° to –50°C.
Freeze Dry Capacity
The volume of a sample that can be freeze dried at one time is
related to factors discussed previously and the size and design of
the freeze dry system. With any given instrument, the capacity is
based on the surface area of the sample; the eutectic temperature
and concentration of the sample; and the rate and amount of heat
transferred to the frozen sample. Of these factors, the eutectic
temperature is the most important factor in determining the amount
of sample that can be freeze dried at one time, particularly when
flasks are used. This is because as the eutectic temperature
decreases, the vapor pressure decreases but the rate of heat
absorption by the sample does not change. This tends to promote
melting of the sample, which leads to a marked increase in vapor

Chapter 1: Introduction
pressure and ultimately overloads the collector and vacuum pump.
Samples that have eutectic temperatures of –20°C or lower should
be placed on the freeze dry system one flask at a time so that the
vacuum in the system may recover before adding another sample
to the system. If the vacuum does not recover, the capacity of the
freeze dry system has been exceeded and the sample should be
removed.
If there is a problem with a particular type of sample melting when
placed on the freeze dry system, dilution of the sample with more
water or providing some insulation around the flask to decrease the
rate of heat absorption by the sample may help. If the eutectic
temperature of the sample is –40 to –60°C, the freeze dry system
selected for use must be equipped with cascade type refrigeration
so that the collector temperature can be cooled to below –75°C, or
a dry ice/solvent trap may be used between the collector and the
vacuum pump.
Samples Containing Volatile
Substances
In certain cases the solvent in a sample to be freeze dried may
contain volatile components such as acetonitrile, methanol, acetic
acid, formic acid or pyridine. In addition to these substances
having an effect on the eutectic temperature, they may increase the
vapor pressure at the surface of the sample. Also, compared to
water, they will require the absorption of less heat for sublimation
to occur. Hence, samples that contain volatile substances will have
a greater tendency to melt, particularly when placed in flasks or
exposed to room temperature. If a sample containing a volatile
substance tends to melt when placed on a freeze dry system,
dilution of the sample with more water will help keep the sample
frozen. For example, a 0.2M solution of acetic acid is much easier
to freeze dry than a 0.5M solution.

Chapter 3: Getting Started
If you did not receive one or more of the components listed for
your Freeze Dryer, or if any of the components are damaged,
contact Labconco Corporation immediately for further instructions.
Setting Up Your Freeze Dryer
After you verify receipt of the proper components, move your
Freeze Dryer to the location where you want to install it. Then,
follow the steps listed below.
Component Orientation
The refrigeration system in the Freeze Dryer draws air in through
one side of the cabinet and exhausts air out through the other side.
A minimum of 3" should be allowed between the sides of the
Freeze Dryer and the adjacent wall surface. Restriction of the
airflow through the cabinet during operation could adversely affect
performance.
After the console model is positioned at the location where it will
be operated, it should be securely attached to the floor. Use (2)
1/4" x 5.0 long wood screws or lag bolts if the floor is wood or
concrete anchors if the floor is concrete. Two .312 diameter holes
are located in the floor of the lower cabinet. Using these holes as a
template, mark the floor directly under the two holes. Roll the
console Freeze Dryer aside and drill suitable pilot holes for the
selected screws/anchors. Install the vacuum pump prior to securing
the console Freeze Dryer to the floor. Roll the console Freeze
Dryer back into position and install the screws/anchors through the
holes in the cabinet floor and into the building floor.

Make certain that the oil in the vacuum pump is
at the proper level.
Place the vacuum pump near the benchtop Freeze Dryer models.
For console models, from the back of the unit, place the vacuum
pump on the floor of the cabinet.
)
TO MAXIMIZE THE STABILITY OF THE
CONSOLE FREEZE DRYER, POSITION THE
VACUUM PUMP AS CLOSE TO THE CENTER
OF THE CABINET FLOOR AS POSSIBLE.
Connect the vacuum pump power cord to the receptacle on the
back of the cabinet labeled “vacuum pump.” If the vacuum pump
has an off/on switch, turn the switch on. The vacuum pump will
be controlled by the Freeze Dryer. Connect the vacuum pump inlet
port to the vacuum tube on the back of the cabinet with the vacuum
hose and clamps provided. If necessary, cut the hose to proper
length to allow for gentle bends without kinks.
Models rated for use on 230V have a reverse IEC connector for
attaching the vacuum pump power cord. A plug is supplied that
can be installed on the vacuum pump power cord if necessary.
Electrical Connection
Plug the power cord into the receptacle on the back of the Freeze
Dryer and plug the other end into a suitable power receptacle.
Chemical Resistance of Freeze
Dryer Components
The FreeZone Freeze Dry System is designed to be chemically
resistant to most compounds that are commonly used in freeze
drying processes. However, by necessity, the freeze dryer is
comprised of a number of different materials, some of which may
be attacked and degraded by certain chemicals. The degree of
degradation is dependent on the concentration and exposure
duration. Some of the major components of the FreeZone Freeze
Dry System that are susceptible to degradation are as follows:

Most common compounds used in freeze drying processes, if
allowed to enter the vacuum pump, will degrade the oil and
cause damage to the vacuum pump.
Sugars and proteins typically will have minimal negative effect
on any of the materials of construction.
When using compounds in the Freeze Dryer that are hostile to the
materials of construction, it is imperative the equipment is
thoroughly cleaned after use.

Rubber and plastic components that have been exposed to
damaging compounds should be removed and flushed with
water.
The oil in the vacuum pump should be checked often. It must
be changed if it is cloudy, shows particles or is discolored. The
useful life of vacuum pump oil can be extended if the vacuum
pump is operated for an extended period of time after a freeze

dry run. This allows contaminants to be purged from the hot
oil. This must be done with the inlet to the pump blocked off
to prevent air from free flowing through the pump. This is
accomplished by closing all sample valves on a clean, dry
freeze dry system and turning on the vacuum pump. If the
pump is operated at an elevated vacuum level (> 10mBar), oil
may be expelled from the pump and damage could occur.
Another way to extend the life of the vacuum pump is to install an
optional secondary trap in the line between the Freeze Dryer and
the vacuum pump. Contact Labconco for ordering information.
With prudent maintenance the FreeZone Freeze Dry System will
provide years of service. Warranty on the affected parts will be
voided if maintenance has been obviously neglected. If you have

Operation Checklist
The following checklist should be followed prior to each use of
your Freeze Dryer:
1. Wipe the interior of the collector chamber with a soft cloth or
paper towel to remove any accumulated moisture.
2. Check the collector chamber drain hose to ensure that the hose
is free of moisture and that the drain plug is securely installed.
The Freeze Dryer will not start if moisture is detected.
3. Using a soft, lint-free cloth or paper towel, wipe the collector
chamber lid gasket to remove any dirt and contaminants that
could cause a vacuum leak. Vacuum grease is not required on
the lid gasket to obtain a proper vacuum seal.
4. Check that each sample valve is closed or in the “vent”
position.
Vacuum Pump Ballast Setting
Most vacuum pumps are equipped with a gas ballast mechanism.
The freeze dry process requires high vacuum. Therefore, it is
recommended that the gas ballast be closed during the operation of
the Freeze Dry System. If the gas ballast is left open for extended

Chapter 4: Using Your Freeze Dryer
vacuum level is <0.133 mBar, the green LED will be lit steadily
indicating that samples may be added.
Setting the Operating Vacuum
Level
The vacuum level may be set by the user to optimize the freeze dry
process. Normally, the sublimation rate will increase if there is
less vacuum (a higher pressure) in the Freeze Dryer. A good
starting place is to set the vacuum so its level is equivalent to about
10°C colder than the eutectic or collapse temperature of the
sample. Adjustments to the vacuum level must be made for
various freeze drying conditions. Factors that must be considered
are whether the sample is freeze dried on heated shelves or in
glassware attached to manifold valves, the volatility of the sample
itself, the size of the sample and the heat energy supplied to the
sample.
When the vacuum control is set to operate at less vacuum, the ice
holding capacity of the collector may be decreased. This can be
improved by installing a baffle in the collector. See Appendix D
Freeze Dryer Accessories for the baffle part number. Position the
baffle with the notches in the tube downward straddling the
collector coil and fittings on the bottom of the chamber.
Some guidelines for setting the Freeze Dryer are shown below.
These show pre-freezing temperatures and vacuum levels. Exact
protocols must be determined by the user for the specific samples
that are being freeze dried.

Pre-Freezing Samples
Appropriate containers for freeze drying include ampules, serum
bottles, and wide mouth freeze drying flasks. Shell freezing of
samples is recommended for wide mouth freeze drying flasks.
Smaller samples in ampules and serum bottles may be frozen in a
22

Chapter 4: Using Your Freeze Dryer
freezer. The sample container size should always be at least two to
three times the sample size (i.e., 40 ml samples should be prepared
in 80 ml containers or larger). The temperature required for prefreezing is dependent on the characteristics of the sample. Prefreezing temperature typically is at least 10° to 20°C below the
eutectic or collapse temperature of the sample.
Adding Sample
The following procedure should be followed when using sample
valves in the freeze dry process:
1. Connect a pre-frozen sample to a sample valve on the drying chamber
or manifold using an adapter. Turn the plastic valve knob to the
“VACUUM” position to open the valve. The bevel on the knob
should be positioned toward the sample port to apply vacuum to the
sample.
Bevel in “vent” position
Vent/Backfill Port
Bevel in “vacuum”
position
Adapter
2. Before adding another sample, allow system vacuum to return
to 0.133 mBar or lower. Any combination of valves and
sample sizes may be utilized at one time provided that the
system vacuum and collector temperature remain sufficiently
low to prevent melting of the frozen sample.
3. When all the frost has disappeared from the outer surface of the
sample container and no cold spots can be detected by handling
the container, the sample is nearly dry. To be certain of low

23
Chapter 4: Using Your Freeze Dryer
final moisture content, dry the sample for several hours past
this point.
4. To remove a container after drying is complete, turn the plastic
knob on the valve to the “VENT” position, which closes the
valve and vents the container. Should backfilling with an inert
gas be required, connect the gas supply line to the vent port on
the valve before turning the plastic knob on the valve to vent
position. The sample container may now be removed. In the
vent position the bevel on the valve knob should point away
from the sample port.
5. Ampules may be flame sealed while connected to a valve by
using a sealing torch. Care must be taken not to burn the valve.
An insulation material placed between the valve and the torch
is recommended.
Shut Down
At the end of a run or when a sufficient amount of condensate
accumulates on the collector coil to obstruct the flow of vapor to
the collector chamber, the Freeze Dryer should be defrosted. First,
release system vacuum by turning the plastic knob on a valve to
the open position or by pulling the collector chamber drain plug
out of the drain hose. Now press the Vacuum Switch on the
control panel to turn the vacuum pump OFF. Press the
Refrigeration Switch next to the illuminated LED to turn OFF the
refrigeration system. Turn OFF the Main Power Switch on the
right-hand side of the cabinet.
Defrosting
The following procedure should be followed when defrosting the
collector coil:
1. Pull the collector chamber drain hose out from the left hand
side of the Freeze Dryer and remove the drain plug. Place the
drain hose in a suitable container to collect the condensate that
will melt off the collector coil.
2. Remove the collector chamber lid and allow ambient room air
to melt the ice. Dispose of the liquid appropriately.
3. Flush the collector chamber with water and wipe chamber dry.
4. If rapid defrost is desired, pour warm water over the collector
coil. Do not fill the chamber above the collector coil as water
will enter the vacuum standpipe and drain into the vacuum
pump.
5. Reinstall the drain hose plug and slide drain hose back into the
side of the cabinet. Dispose of the liquid appropriately.

!
Utilization of acid requires immediate cleaning
and neutralization after defrost or physical
damage to the collector chamber and collector
coil will result.
Do not attempt to chip ice from the collector coil
as damage may occur to the coil.
Never attempt to start the vacuum pump when
there is liquid in the collector chamber. This
could result in damage to the vacuum pump.
Alarms
A number of unusual events may occur during a lyophilization
procedure that can adversely effect the operation of the Freeze
Dryer. If an event occurs, the alarm indicator will flash and the
beeper will sound.
The beeper will automatically mute itself after one minute. The
specific alarm can be identified by pressing MENU. Pressing
MENU multiple times will display multiple alarms if they have
occurred. The following “out of specification” conditions will
initiate an alarm:
Power Failure
If a power failure occurs during a Freeze Dry process, the vacuum
control valve will allow air to bleed into the Freeze Dryer System.
If the failure is of a short duration and the collector does not warm
excessively, when power is restored the Freeze Dryer will restart
and resume operation of the refrigeration and vacuum systems. If
the power failure lasts for a longer duration and the collector
warms above safe limits, when the power is restored, the Freeze
Dryer will not automatically restart. This prevents melted sample
from being drawn into the collector and prevents liquid from being
sucked into the vacuum pump.
When power is restored, the alarm indicator will flash and the
alarm beeper will sound. When the MENU button is pressed the
display will show
POWER FAIL

should be regularly monitored to verify that it is clean.
Moisture in Collector
If there is liquid in the collector chamber and either a
REFRIGERATION button or the VACUUM button is pressed,
neither function will start and an alarm will be activated. When
MENU is pressed, the display will show:
MOISTURE IN COLLECTOR
When the collector is drained, the alarm will self-cancel.
This feature prevents the inadvertent start of the vacuum pump
when liquid is in the collector and thereby can extend the life of
the vacuum pump. A few drops of liquid may remain in the drain
hose after draining. When the vacuum pump is started these drops
may be sucked into the collector chamber. This is normal.

CHAPTER 5
MAINTAINING YOUR
FREEZE DRYER
Under normal operation, the Freeze Dryer requires little
maintenance. The following maintenance schedule is
recommended:
As needed:
1. Clean up all spills; remove liquids from the chamber.
2. Clean lid and gasket using soft cloth, sponge or chamois and a
mild, non-abrasive soap or detergent.
3. Check oil level of the vacuum pump. It should be between
MIN and MAX. If the oil level is less than an inch (25.4 mm)
above MIN, add oil to proper level.
4. If oil shows cloudiness, particles or discoloration, drain the
pump and replace with fresh oil.
5. Utilization of acids requires immediate cleaning and
neutralization after a run or physical damage to the
collector chamber and collector coil will result.
6. Check the collection chamber for condensed or frozen solvents
and dispose of appropriately. Completely empty the collector
chamber before the next run or before attempting to start the
vacuum pump.
28

Chapter 5: Maintaining Your RapidVap
7. If sample valves leak or stems become difficult to turn, pull the
stem out of the rubber valve body and apply a thin coat of
vacuum grease to the stem. Reinsert the stem into the valve
body.
Monthly:
1. The rubber components on the Freeze Dryer may eventually
deteriorate and require replacement. The effective life of
rubber parts depends upon both their usage and the surrounding
environment. Check all rubber hoses and gaskets and replace
any that show signs of hardening, permanent set or
deterioration.
2. Using a soft cloth, sponge or chamois and a mild, non-abrasive
soap or detergent, clean the acrylic chamber lid.
3. Using a soft cloth, sponge, or chamois and a mild, non-abrasive
soap or detergent, clean the exterior surfaces of the Freeze
Dryer. Liquid spray cleaners and polishes may be used on the
exterior surfaces. Do not use solvents to remove stains from
the exterior surfaces as they may damage the finish.
Annually:
1. Every 12 months, or more often if the Freeze Dryer is operated
in a dusty environment, the refrigeration system condenser
should be cleaned. Using a vacuum cleaner with brush
attachment, clean the condenser to ensure proper airflow for
peak performance.

TROUBLESHOOTING
Refer to the following if your Freeze Dryer fails to operate
properly. If the suggested corrective actions do not solve your
problem, contact Labconco for additional assistance.
Labconco Freeze Dry Systems that are clean, dry and without
samples attached should reach a vacuum of 0.133 mBar within 10
minutes and should achieve an ultimate vacuum of 0.033 mBar
within 18 hours when the refrigeration is operating. If the Freeze
Dryer does not obtain a satisfactory vacuum, perform the following
maintenance tests.
I. Vacuum Pump
First make sure that the vacuum pump operates. If it fails to
operate, check the electrical connections of the Freeze Dryer to the
power source and then check the electrical connection of the
vacuum pump to the Freeze Dryer. If the vacuum pump has a
power switch, make sure that it is turned on. If the vacuum is not
adequate when the vacuum pump is operating, proceed with the
following steps:
1. Check the oil and ensure it is clear and clean. If the oil
looks cloudy or has any particulates, replace the pump oil.
Sometimes it may be necessary to flush the pump with
clean oil several times. To flush the pump, run the pump 5
to 10 minutes to allow the oil to warm up. Drain the oil
and refill with clean oil. Repeat as necessary.

Chapter 7: Troubleshooting
2. Check the oil level in the pump. Ensure it is filled to the
correct level.
3. Check vacuum hose connections from the pump to the
Freeze Dryer and try running the unit.
If vacuum problems continue, consider obtaining a second vacuum
gauge capable of reading a vacuum of 0.010 mBar. It is often
useful in determining if the vacuum pump is operating properly
and the vacuum sensor reading is accurate.
4. Isolate the pump by disconnecting the vacuum hose from
the Freeze Dryer. Deadhead the pump by inserting the
vacuum sensor from a secondary vacuum gauge into the
end of the vacuum hose and observe the vacuum reading
obtained. Confirm that the pump is capable of achieving an
ultimate vacuum less than 0.010 mBar or approximately 10
microns. If an inadequate vacuum reading is obtained, the
pump has most likely failed and may need to be replaced or
rebuilt.
II. Gaskets, Tubing, Connections, Sample
Valves
1. Check all sample valves on the drying chamber/manifold
and ensure all valves are closed or in the vent position.
Check to ensure all fittings are tight and sealed properly
against the chamber. Inspect valves for cracks or cuts.
2. Inspect gasket(s) for cracks or defects. Ensure the gasket is
clean. Apply a thin coat of vacuum grease to the gasket.
Keep in mind too much vacuum grease can actually cause
leaks.
3. Check the drain line and ensure the drain plug is installed
and the tube appears to be in good condition.
4. Check all rubber vacuum tubing for signs of deterioration
or cracking.
5. Check all connections and make sure they are secure and
leak tight.
6. When checking the sample valves, pull as much vacuum as
possible. If a vacuum indication is displayed, wiggle or
rotate the valves and watch the gauge for any fluctuations.
Fluctuations can indicate a potential vacuum leak. If the
valve seems to be in good condition, remove the valve and
apply a thin coat of vacuum grease to the stem and the
outside sealing surface of the valve body, and reinstall the
valve. DO NOT APPLY VACUUM GREASE TO THE

Product Service: Domestic 1-800-522-7658, International 816-333-8811
Chapter 7: Troubleshooting
SAMPLE VALVE GASKETS, WHICH SEAL TO THE
WALL OF THE DRYING CHAMBER. If the valve still
seems to be the source of the problem, remove the valve
and stopper the hole with a rubber stopper. Continue
checking the other valves.
7. Make sure that the sample valve bulkhead nuts are tight.
Either tighten by hand or use the wrench supplied with
chambers. To use the wrench, first remove the knob and
stem assembly and also the valve body. The pins on the
wrench fit into the round holes of the nut. The nut should
be snug, but avoid over tightening. Replace the valve
body, knob and stem assembly.
The illustrations below show how the sample valve installs on
a chamber and a manifold.

III. System Components and Collection

The following test is used to check the collection chamber integrity
and connections. The figure below points out potential areas to
locate a leak.

Bulkhead
Fitting
•
Fill the collection chamber with approximately 2 inches of
water, enough to cover all fittings. Remove one wire from the
moisture sensor. Replace the collection chamber lid and turn
on the vacuum pump. Allow the vacuum pump to run for
approximately 5 to 10 seconds. (If the vacuum pump is left
on, the water will begin to boil and the test will not be
effective). Look inside the chamber for any bubbling while
the pump is running and after you shut the pump off.
•
If bubbling is observed around the bulkhead fittings, access
the bottom of the chamber and remove the insulation. Tighten
the appropriate fitting by placing a wrench on the fitting inside
Product Service: Domestic 1-800-522-7658, International 816-333-8811
Chapter 7: Troubleshooting
the chamber and use a second wrench to turn the nut on the
bottom of the chamber. Be careful not to damage the
evaporator coils or the brazed joints to the refrigerant system.
Once the fitting is tightened, perform the test again. Should
the bubbling still be present, loosen the bulkhead fittings and
apply vacuum grease to the O-rings, then reassemble and test.
•
If bubbling was observed on the chamber surface, the chamber
must be replaced. This type of leak cannot be successfully
repaired. The leading cause of a chamber surface leak is
corrosive residue left in the chamber after use.
Refrigeration Module Operation
Under a no-load condition, the FreeZone Single Stage Freeze Dry
System can achieve a collector temperature of –47°C or lower
within 40 minutes when the vacuum pump is running, depending
on ambient temperature and humidity.
If any repairs are required on the refrigeration module, contact
your local laboratory supply dealer. If your laboratory supply
dealer is unable to provide assistance, please call Labconco.
Repairs should only be undertaken by a competent refrigeration
technician or through an authorized Labconco service agency.

CHAPTER 8
MODIFYING YOUR
FREEZE DRYER
DISPLAY
Your Freeze Dryer has been carefully calibrated and tested before
shipping, however under certain circumstances it may be necessary
to adjust the calibration of the temperature and/or vacuum display
or to modify alarm points. Adjustments may be necessary if the
Freeze Dryer requires service or if it is operating on a line voltage
outside the voltage range at which the alarm was preset. This
DOES NOT mean that the Freeze Dryer may be operated at a
voltage outside the ranges shown in Appendix C.
Temperature and Vacuum Display
An offset may be added to the collector temperature or vacuum
display. Use an accurate traceable reference to compare the
readings.
Temperature offset may be varied ±5°C in 1°C increments.
Vacuum offset may be varied ±0.020 mBar in 0.001 mBar
increments.
Line Voltage Alarm Points
The Freeze Dryer is designed to alarm if the line voltage varies
more than ±10% from nominal line voltage. Models rated to
operate on 115V are preset to alarm if the voltage drops below
approximately 103V or rises above approximately 127V. Models
rated to operate on 230V will alarm if the voltage drops below
approximately 206V or rises above approximately 254V. Some
models are designed to operate below these ranges (see Appendix
C). In these cases it is permissible to lower the low voltage alarm
point to prevent nuisance alarms from occurring.
Chapter 8: Modifying Your Freeze Dryer Display
Low line limit may be lowered in 5 increments of
approximately 2 to 3V increments for 115V models or
disabled.
Low line limit may be lowered in 5 increments of
approximately 4 to 5V increments for 230V models or
disabled.
High line limit may be raised in 5 increments of
approximately 2 to 3V increments for 115V models or
disabled.
High line limit may be raised in 5 increments of
approximately 4 to 5V increments for 230V models or
disabled.
Moisture Sensor Alarm
The moisture sensor alarm may be disabled. It is shipped enabled
as the factory default setting.

Lyph-Lock® Flasks
Borosilicate glass
adapters with
either 19/38 or 24/40
standard taper joints
have 90° bend.
(Required — order
separately.)
Compatible with
all major
brands of laboratory freeze
dry apparatus.
Only three pieces
per flask — no
Lyph-Lock Flasks simplify your lyophilization procedures
because they have only three pieces per flask — a high
strength borosilicate glass top and bottom with a silicone
rubber ring seal. The unique wide-mouth design helps you
load samples easily and lyophilize efficiently.
How to select Lyph-Lock Flasks for
your Freeze Dry System
Select the Lyph-Lock Flasks based on your sample sizes.
Flasks should be filled to no more than one-third of their
volume so that maximum surface area is achieved and efficient lyophilization is ensured. A complete Lyph-Lock Flask
includes a glass top and bottom and a rubber ring seal. Tops,
bottoms and seals are available separately as replacement
components. Adapters are required to attach flasks to freeze
dry valve ports.

7593000 Adapter connects to valve ports for manual stoppering of 20 mm corkage serum bottles under original vacuum. The stopper and serum bottle are inserted into the
adapter body and lyophilization begins. After the process is
completed, the researcher slides the stopper into position
so when the valve is turned from vacuum to vent the serum
bottle is tightly sealed by the stopper. The ejector tube is
then used to force the serum bottle out of the adapter.
