Ai UL/CSA SolventVap 2.6-Gallon/10L Rotary Evaporator w .

A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. The process of rotary evaporation is most often used to separate solvents with low boiling points, such a n-hexane or ethyl acetate, from compounds which are solid at room temperature and pressure.

Rotary Evaporation to Remove Solvent | Protocol

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 combined with reduced pressure to evaporate, dry, and purify samples for further downstream use.

Acetic Acid - Common Organic Chemistry

The common name for undiluted acetic acid is glacial acetic acid. With a melting/freezing point of around 16 C, acetic acid is not a suitable solvent for reactions that require cooling. In fact, when removing acetic acid by rotovap it tends to crystallize on the cold finger of the rotovap rather than dripping into the collection flask as a liquid.
