Useful information

Distillation is a thermal separating process for liquid compounds based
on substance-specific, pressure-dependent boiling points through eva-
poration 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 con-
stant 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 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 Woulff bottle and/or a vacuum
separator.
Working with a jet pump to create a vacuum can only be recom-
mended 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%.

For protection of the equipment
• The voltage stated on the type plate must correspond to the mains
voltage.
• Socket must be earthed (protective ground contact).
• Removable parts must be refitted to the appliance to prevent the
infiltration of foreign objects, liquids etc.
• Protect the appliance and accessories from bumps and impacts.
• The appliance may only be opened by experts.
The safety of the user cannot be guaranteed if the appliance is ope-
rated with accessories that are not supplied or recommended by
the manufacturer or if the appliance is operated improperly contrary
to the manufacturer's specifications.

This corresponds to condensation on approx. 2/3 of the cooling coil.
With larger capacities there is the risk that the uncondensed solvent
vapour will be extracted.
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 evaporator piston is automatically lifted out of
the heating bath by an integrated gas spring.
CAUTION! The maximum load (evaporator piston and contents) is
1.5 kg for a permissible safety lift with no power for glass apparatus
with diagonal or vertical condenser.
When using other types of condensers such as dry ice or intensive
condensers as well as when using return distillation distributors with
slip-on condensers, it may be necessary to reduce the mass of the
media to compensate for the mass of this additional glassware.
Thus, prior to distillation, check whether the lift goes up without
power when laden with the glass and distillation material.
