Rotary evaporators (also known as “Rotovaps”) are mainly used for distillations/separation applications often used for medicinal chemistry, pharmaceutical, chromatography, and petrochemical fields. In summary the system 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
(3) heating the solution
(4) then the evaporated solvent then condenses in a cooled glass condenser
