BUCHI Rotavapo R-215 - Manual (Page 26)

4 Description of function
26 R-210/215 Operation Manual, Version F
c Cooling area
The solvent vapor flows very quickly into the condenser. Here, the energy in the solvent vapor is trans-
ferred to the cooling medium (mostly water), so that the solvent condenses.
d Receiving flask
The receiving flask collects the condensed solvent.
Vacuum
The vacuum reduces the boiling temperature and thus increases the distillation performance.
The evaporating performance is influenced by the distillation pressure (vacuum), the heating bath
temperature, and the rotation speed and size of the evaporating flask.
For information on the optimum distillation conditions, see chapter Operation.
