Rotary Evaporation to Remove Solvent | Organic Chemistry

Rotary evaporation is a technique commonly used in organic chemistry to remove a volatile solvent from a non-volatile compound of interest. Invented by Lyman C. Craig in 1950 the rotary evaporator, or rotovap, gently removes solvents from compounds using heat coined with reduced pressure to evaporate, dry, and purify samples for further downstream use.

Rotary Evaporator

A rotary evaporator (sometimes abbreviated to rotavap) is a piece of equipment primarily used to remove solvent from a sample through “evaporation under reduced pressure”. The presence of reduced pressure in the apparatus causes the solvent (in the round bottom flask) to boil at a lower temperature than normal.
