a
Evaporation area
The solvent is heated by means of a heating bath. The turbulent mixing inside the rotating
evaporating ask results in an increased evaporation rate.
The drive unit oers a wide range of rotational speeds to perfectly match dierent evaporation
tasks. It also leads to an even mixing of the sample, thus preventing stationary overheating in
the ask. When drying powders or pasty materials, the rotation ensures smooth and
thorough drying.
b
Cooling area
The solvent vapor quickly enters the condenser. Here, the energy in the solvent vapor is
transferred to the cooling medium (mostly water), so that the solvent condenses.
c
Receiving ask
The receiving ask collects the condensed solvent.

For information about optimum distillation conditions see section 6, Operation.
