What is a Rotary Evaporator? - Asynt

The rotatory evaporator working principle is that the boiling point of liquids lowers on decreasing their pressure. This allows the solvent to vaporize at lower temperatures than when boiled in a normal atmosphere. You should choose a vacuum pump for your rotavap that will guarantee an improved evaporation efficiency.
