Distillation is a thermal separating process for liquid compounds
based on substance-specific, pressure-dependent boiling points
through evaporation and subsequent condensation.
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 boi-
ling point is set with a steam temperature of approx. 40 °C. The
cooling water for the condensation cooler should not be warmer
than 20 °C (60-40-20 rule).
A chemical resistant membrane pump with a vacuum controller
should be used to create the vacuum. The pump is protected from
solvent residue by the addition of a condensate flask and/or a
vacuum separator. Working with a jet pump to create a vacuum
can only be recommended to a limited extent as the solvents may
contaminate the environment when using these systems.
Speed, temperature, piston size and system pressure all affect the
evaporator air capacity.
The optimum capacity of the flow-through condenser is approx.
60%.
This corresponds to condensation on approx. 2/3 of the cooling
coil.
With larger capacities there is the risk that the uncondensed sol-
vent vapor will be extracted.

In order to prevent this, the condenser loading safety monitoring
system can be activated. Before activating the safety monitoring,
first carry out several distillations, noting the value given under
menu option "EVAPORATOR  Advanced  Max power of coo-
ler". Now calculate the heat rejection rate using the following
formula:
Cooler power limit = Max power of cooler * 1.3
Enter this value under menu option "EVAPORATOR  Advanced
 Cooler power limit". The device will now stop the measure-
ment and issue an error message if the threshold for the conden-
ser is exceeded. If the configuration of the condenser equipment
or the distillation process is modified, then it may be necessary to
re-evaluate the maximum condenser loading.
The device is equipped with a piston-operated safety mechanism.
The glass apparatus may contain a vacuum following interruption
to the power supply; vent the system before switching back on.
If the power cuts out, the evaporation flask is automatically lifted
out of the heating bath by an integrated gas spring.
The safety lift must be checked daily
CAUTION
prior to operation. For more informati-
on see the section "Safety Instructions
– Safety Lift"!
