What is the purpose of using the rotary evaporator?

The rotary evaporator functions on the general assumption that the boiling point of the solvent is much lower than that of the liquid surrounding it. It also assumes the compounds in the liquid are thermally sensitive; otherwise you could just boil the solvent out. A rotovap works by creating a vacuum in a rotating glass flask.

A rotary evaporator (or rotavap/rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.. The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid).
