Rotary Evaporator Theory

Rotary evaporators are commonly used in chemistry related environments for the efficient and gentle removal of solvents from samples by evaporation 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 flask wall surfaces so it can evaporate easily.

Talk:Rotary evaporator - Wikipedia

The entire purpose behind rotary evaporators is the production of a thin film of the solution on the surface of the flask as it rotates above the surface of the solution. This thin film evaporates more easily than solvent right at the surface at the bulk of the solution. thus the angle and the rotation are necessary to create this thin film.
