The Rotary Evaporator

2. Next, cold water is circulated through the rotovap condenser to condense the volatile solvent on the condenser coils and to prevent, as much as possible, the volatile solvent from vaporizing into the aspirator. Ice and a small amount of water are placed in the water-circulating pump. The circulating pump is plugged in. 3.

What is the purpose of using the rotary evaporator? - Lab ...

A rotary evaporator (or rotavap/rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.. The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid).

How Rotary Evaporator Xp Work -

How does the rotary evaporator work? The rotovap works by increasing the rate of evaporation of the solvent by (1) reducing the pressure to lower the solvent boiling point, (2) rotating the sample to increase the effective surface area and (3) heating the solution. To use the rotovap, first make sure that the power is on (top right of the stand).
