What is a Rotary Evaporator?

Feb 14, 2022 Rotary evaporators work on the principle that solvents have a range of boiling points, which decrease under reduced pressure. The evaporation flask rotates at a specified speed forcing the materials to form a large area of thin film on the inner wall of the flask. The flask is heated evenly, and materials with a lower boiling point rapidly ...
