Even though the polyscience rotary vacuum evaporator looks pretty complicated, it's really pretty simple. The purpose of the evaporator is to remove low boiling organic chemicals, usually solvents, from a mixture of compounds. The rotary evaporator is the method of choice for solvent removal in the modern organic laboratory. The solvents or low boiling compounds are removed by a simple distillation. The rotary evaporator is designed to be operated under a vacuum (to lower a compound's boiling point) while heating the sample at the same time. A cold finger is used to condense the vapors to a liquid, which are trapped in a separate flask.
Important Features of the rotary vacuum evaporator:
1) The vacuum pump is the source of reduced pressure in the system.
2) Spin speed and bath temperature control knobs.
3) Water bath.
4) Bump guard.
5)Cold finger. (Please do not use the rotovap if the finger is not cold. There should be excess solid dry ice in the finger.)
6)Vacuum release valve.
