How to use a Rotary Evaporator

Apr 01, 2010 A typical rotary evaporator has a water bath that can be heated in either a metal container or crystallization dish. This keeps the solvent from freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser and is collected for easy reuse or disposal.

The operation methodology of a Rotary vacuum evaporator is depicted in Fig. 6.14. There is a general 20/40/60 rule. It states that the temperature of the water bath should be 60 C, causing a temperature of 40 C of the sample and the vapor evolved is thereafter condensed at 20 C. For lower temperature ranges, a 0/20/40 rule is applicable.

When the lift moves downward, the evaporating flask displaces the already filled in water or oil. To prevent the heating bath from overflowing: Prior to filling, move the lift with the mounted evaporating flask downward. Only then fill the water or oil up to at most the upper mark of the heating bath tank.
