Distillation is a thermal separating process for liquid com-
pounds based on substance-specific, pressure-dependent
boiling points through evaporation and subsequent con-
densation.
The boiling point temperature decreases with decreasing
external pressure which means that work is usually done
under reduced pressure. In this way the heating bath can
be maintained at a constant temperature (e.g. 60 °C).
Using the vacuum, the boiling point is set with a steam
temperature of approx. 40 °C. The cooling water for the
condensation condenser should not be warmer than 20 °C
(60-40-20 rule).
A chemical resistant membrane pump with a vacuum con-
troller should be used to create the vacuum. The pump is
protected from solvent residue by the addition of a con-
densate flask and/or a vacuum separator.

Apply the cylindrical M5x25 (2) (4x) and the serrated
washer M5 (1) (4x) to mount the base (3) with the lift
unit (4) after you unpack the package.
• Fix the switching adapter
Attach the switching adapter on the rear side and secure
it with the brackets.
- Insert the switching adapter into the upper bracket. (2)
- Bend down the lower bracket and push the switching
adapter into it. (3)
- Connect the low-voltage connector to the connection
socket and fix it with the clamp. (4) (5)
- Plug the power cord in the switching adapter and
connect it to the power supply of the valid voltage.
After connecting to the power supply, the power indicator
will light up. (6)
Useful information
Working with a jet pump to create a vacuum can only be
recommended to a limited extent as the solvents may con-
taminate the environment when using these systems.
Speed, temperature, flask size and system pressure all af-
fect the evaporator air capacity.
The optimum capacity of the flow-through condenser is ap-
prox. 60%.
This corresponds to condensation on approx. 2/3 of the
cooling coil. With larger capacities there is the risk that the
uncondensed solvent vapor will be extracted.
The device is designed for operation with a cooling water
supply system (e.g. laboratory thermostat), but can also be
run off a water supply line. Please refer to the "Technical
Data" for information on cooling water pressure, tempera-
ture constancy, and flow rate.
