A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporation is most often and conveniently applied to separate low boiling solvents such a n-hexane or ethyl acetate from compounds which are solid at room temperature and pressure.

Is rotary evaporator distillation?

A rotary evaporator is a specially designed instrument for the evapora- tion of solvent (single-stage or straight distillation) 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 wall surfaces and can evaporate easily. Click to see full answer.
