How to use a rotary evaporator? - Lab Instrument Manufacturer

Rotary evaporator (also called "rotavap") are used to remove solvents from reaction mixtures and can accommodate volumes as large as 3 liters. They are found in almost every organic laboratory, since they allow performing this task very quickly. A typical rotary evaporator has a water bath that can be heated in either a metal container or crystallization dish.

Rotovap features a specially designed motor and worm gear, which provides constant rotation at speeds from 10 to 180 rpm.As the flask containing the solvent is rotated, it continually transfers a thin layer of liquid over the entire inner surface. This gives a very large surface area for evaporation, which is caused by the gentle heating from the water bath.
