Most 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 concentrate for removing solvents efficiently via the process of evaporation
It is used to remove solvent from a sample through “evaporation under reduced pressure”.
At this point, the solvent boils and produces vapor.
The vapor condenses through the condenser and drips into a separate receiving flask.
