Rotary Evaporation: Laboratory Applications

Rotary evaporators are commonly used in chemistry related environments for the efficient and gentle removal of solvents from samples by evaporation under vacuum. The evaporator consists of a heating bath with a rotating flask, in which the liquid is distributed as a thin film over the hot flask wall surfaces so it can evaporate easily.
