THE PROCESS

Rotary evaporation is the process of reducing the volume of a solvent by distributing it as a thin film across the interior of a vessel at elevated temperature and reduced pressure. This promotes the rapid removal of excess solvent. Rotary evaporators have four major components: heat bath, rotor, condenser, and solvent trap. Additionally an aspirator or vacuum pump needs to be attached, as well as a bump trap and round bottom flask containing the sample to be concentrated.The fact that a vacuum is applied to the setup means that the boiling points of the solvents are significantly lower than at ambient pressure. Since the flask is rotated during the evaporation process, the surface area is larger than normal which increases the evaporation rate significantly. In addition, this method also avoids overheating of the target compound i.e. oxidation because lower temperatures are used.
