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.
