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.

Lesson Learned - Peroxide Explosion Injures Campus .

A sample from the THF bottle was later analyzed with a simple test and found to contain excessive peroxides (more than 100 mg/l). The evaporation in the rotovap concentrated the peroxides in the bottom of the glass reaction vessel and any movement of the vessel could cause the now dry and shock sensitive peroxides crystals to explode.

20L BVV™ Rotary Evaporator - Closed Loop Extractors

Rotary evaporator's are used in laboratories to gently remove and recover solvents from a given mixture via evaporation. Rotary evaporation is done by heating a mixture while lowering the atmospheric pressure using a vacuum system. This lowers the boiling point of the solvent forcing a phase change from liquid to vapor. The vapor is then pulled into the path of the condenser by the vacuum .
