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.

Rotary Evaporator Enclosure

In the laboratory, a rotary evaporator (rotovap) is employed to remove volatile solvents or isolate components of reaction mixtures by evaporation. This may be done following a separation or extraction process. During rotary evaporation, the solvent is removed under vacuum and is subsequently trapped by the condenser and collected.
