What are Applications of a Rotary Evaporator? - Rotovap

Dec 20, 2019 A rotary evaporator is electronically controlled so that the rotation of the flask can be kept at a constant speed, and the mixture can form a film on the inner surface of the flask, creating a larger surface for heating. All of these factors contribute to the faster evaporation speed of solvent, which means higher efficiency and better accuracy.

Title: Rotary Evaporator Page 1 of 6 ROTARY EVAPORATOR. Rotary evaporators (also called rotavaps or rotovaps) are used to remove solvents from reaction mixtures. Liquid solvents can be removed without excessive heating of the sample by lowering the pressure above a bulk liquid and thus lowering the boiling points of the component liquids in it.
