How to choose a rotary evaporator when doing distillation .

How to choose a rotary evaporator when doing distillation .

The distillation flask of the rotary evaporator can be a pear-shaped or round-bottomed flask with a standard ground port, connected to a pressure reducing pump via a highly refluxing serpentine condenser, and another opening of the reflux condenser with a receiving flask with a grinding port. Connected to receive the evaporated organic solvent. There is a three-way piston between the .

Purification by Steam distillation/crystallisation (Theory .

Purification by Steam distillation/crystallisation (Theory .

If water is used as one of the immiscible liquids the method is called steam distillation. It is also used for purifying liquids which decompose at their normal boiling points. e.g. Glycerol. Steam distillation is used for separating organic compounds from plant parts. e.g. Lemon grass oil, Eucalyptus oil etc.
