what is the usage of a rotary evaporator (rotovap)?

Roto-evaporation (rotovap) requires mechanical rotation of a flask under vacuum. The rotation of the flask increases the surface area of the solvent to be removed, increasing the rate of evaporation, and reducing the risk of “bumping”: when a large pocket of solvent vapor forms rapidly and displaces the surrounding liquid.
