SET-UP
Please read the sections „General Information" and „Safety Instructions" before
you assemble the appliance.

1.
Drive unit
Mount the drive on the support rod (1) with the clamping ring (4). The black screw collar
(9) must face inwards towards the heating bath and the electric power cable (6) must point
down.
Secure the clamping ring (4) with the drive unit by tightening the star grip (5) on the
support rod (1).
Insert the power cable with plug (6) in the correct socket on the rear of the heating bath
housing (2).
Screw the support rod (7) for the condenser in the threaded hole of the coupling (8).
2.
Vapor support tube and evaporation flask
Remove the black screw collar (9), the spring tension ring (10), the PTFE seal (11) and the
silicon ring (12) from the drive.
From the side with the red locking knob (14), insert the vapor tube (A) with the black
support ring (B) in the drive unit as far as the stop. Make sure the side outlet of the vapor
tube is parallel to the support rod (7).
From the bath side, slide the silicon ring (12) - curved
face first - on the vapor tube (A). Then slide the
13
PTFE seal (11) - sealing lip first - on the vapor
support tube as far as it will go.
Place first the screw collar (9) and then the spring
tension ring (10) on the neck of the evaporation flask
(C, D, E) or transition piece (F).
Slide the flange over the vapor support tube (A) and
into the drive up against the seal. Push the flask as
far as it will go and half tighten the screw collar.
To give the screw collar and flask sufficient hold,
press the fastening knob (13) to lock the gear.
3.
Condenser
14
The glass set is easier to mount when the condenser is in
upright position.
The support rod (7) should be vertical. If not, loosen the red
locking knob (14) and pull out the fastening knob (13) so that
the coupling (8) can be swivelled 180°. The fastening
knob (13) will then latch home again and the support rod will be
in upright position. Re-tighten the red locking knob (14).
Screw the butt flange (G) to the threaded socket on the side of
the vapor support tube (A) and insert the sealing ring (G1).
Place the clamp (15) on the support rod (7) and fasten the
condenser (H) to the support rod with the clamp. Make sure that
the condenser's water and vacuum connections are at the top
end. Using the butt flange (G), screw the condenser unit (H) to the vapor tube (A). The
red locking button (14) must be tight in order to provide a secure hold for the condenser
and support rod.
22
E
4.
lnlet tube
Place the screw connection cap (I) and the seal (I1) on the inlet tube (K).
Then insert the inlet tube in the open end of the vapor tube and tighten the screw
connection cap (I). Inlet valve is made of PTFE, please do not grease.
5.
Collection flask
Screw the butt flange (G) on the open end of the condenser (H) and screw the sealing
ring (G1) and the collection flask (L, M, N) or vacuum cap (0) on the other end of the
unit (according to the intended method of distillation).
6.
Setting up for normal distillation
(Starting from the position for reflux
distillation)
For normal distillation the collection
flask has to point down. Slacken the
red locking knob (14), pull out the
fastening knob (13) and swivel the
condenser (with flask and support
rod) through 180° until the fastening
knob (13) latches in the second position. Then re-tighten the red locking
knob (14).
7.
Setting up for reflux distillation
(Starting from the position for normal
distillation)
For reflux distillation the condenser has to be in
upright position and a vacuum cap (0) is used
instead of the collection flask (L). To re-position
the condenser, loosen the locking knob (14),
pull out the fastening knob (13) and swivel the
condenser with flask and support rod through
180° until the fastening knob (13) latches home.
Then tighten the locking knob (14).
8.
Cooling water and vacuum connections
Join the cooling water connections (H2) and the
vacuum connection (H1) to the side of the
condenser and secure with hose clips (not
supplied).

CONTROLS AND OPERATION
Important:
It is imperative to read the section „Safety instructions" and „General
information" before you use the appliance for the first time.
Before connecting the appliance to the power supply, make sure that
your supply voltage is the same as that on the rating plate of the
appliance. Use plugs approved for your country. In this connection,
please read the note in the section „General" on page 19.
o
o
o
o
o
Check all components and make sure they are in working order!
Check all connections for leaks.
Add water, oil or bath liquid to the heating bath. Observe the
max/min level.
Run water or an alternative liquid through the condenser.
Add solution to the evaporation flask.
o
Use the locating knob (16) and
star grip (5) to position the
evaporation flask in the heating bath with a safety
clearance of at least 10 mm between the flask and the
bath wall (see detail view on page 14). The flask
rotation switch (17) is not to be used before this point.
o
The depth of immersion of the evaporation flask in the
bath liquid is set by vertical adjustment of the complete
drive. Holding the drive unit (3) securely, slacken the
star grip (5), move the drive up or down accordinqly
16
and retighten with the star grip.

Use switch (18) to turn on the bath heater (the pilot lamp lights up). You can
select the bath temperature with knob (20).Caution: Risk of scalding when
using the heating bath!
When you are sure that the knob (19) is set to 0 (turn counterclockwise as far as the
stop), use the switch (17) to turn on the flask

rotation (the Pilot lamp lights up). Then you can
use the knob (19) to set the required speed.
You can add solvent to the evaporation flask
when the system is under vacuum. To do so,
connect the inlet tube (K) to a length of tubing
(dia 6 mm) and place the end of the tubing in the
solvent container. Use the valve (K1) to regulate
the required amount of solvent.
You can switch over the VV Micro from reflux
distillation to normal distillation while it is in
operation. Important: Fit a large enough
collection flask before beginning with the distillation. To switch over, release
the locking knob (14), pull out the fastening knob (13) and swivel the condenser
through 180° until the fastening knob (13) latches home. Re-tighten the locking
knob (14).
When the distillation is over, lift the evaporation flask out of the bath by undoing
the star grip (4 and/or 5) and moving the drive unit.
Before you use the appliance in the laboratory for the first time, please check
that its switches, knobs, drive etc. are in working order.
INFORMATION ABOUT DISTILLATION SETTINGS
Using a rotary evaporator for thermal cracking of substances some basic consideration
should be made to achieve the best results possible. Optimize settings as described
below:
10. Rotary speed of evaporation flask
Raise distillation speed by raising rotational speed. This methods cuts distillation time and
protects the substances handled.
11. Temperature difference between hot bath and vapor
This temperature difference should at least be 20 K to reach adequate distillation speed. If
acceptable by thermal stability of the substances handled, you even may raise the
temperature difference.
Rule of thumb: double temperature to double distillation speed.
25
E
12. Temperature difference between vapor temperature and coolant
This temperature difference should be no less than 20 K to guarantee adequate
condensation. Low temperature difference, effectiveness of solvent recovery drops.
Choose an as high as possible temperature difference in particular for high-boiling
substances.
13. Solvent data
Examples for using reference table and nomogram:
This reference table details substance data needed for distillation, whereas the nomogram
reflects relationship between pressure and boil temperature of some solvents. Go by the
Clausius-Clapeyron equation and plot 1/T against log p.
13.1. At boiling temperature of 40°C
Vacuumcontroller: in column "vacuum for boil temperature" use the "Set Vac" nominal
value as depicted for 40°C.
13.2. At boiling temperatures deviating from 40°C
1. On temperature axis of the nomogram mark boil temperature needed.
2. Draw a line to the right and determine intersection with the solvent line.
3. From this intersetion draw a straight line down to determine the vacuum pressure
neeed for this particular application.
13.3. Solvents not depicted
-
The following items might help in determining the right vacuum pressure:
1. Raise of the straight line is a function of evaporation enthalpy. It is similar for similar
chemical substances with similar boil temperature. Hence, straight lines depicted may
be used for rough reference to a lightly deviating boil point.
2. A water jet pump or diaphragm-type pump may lower boil temperature by about 100°C.
3. Rule of thumb: decrease pressure to ½ will decrease boil point by about 15°C.
