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.

How does rotary evaporation work? -

How does the rotary evaporator work? The rotovap works by increasing the rate of evaporation of the solvent by (1) reducing the pressure to lower the solvent boiling point, (2) rotating the sample to increase the effective surface area and (3) heating the solution. To use the rotovap, first make sure that the power is on (top right of the stand).
