The solvent collection flask of the unit should always be emptied prior use to prevent accidentally mixing of incompatible chemicals. SAFETY FIRST! The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated).

Rotary Evaporation to Remove Solvent | Protocol

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.

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 .

What is the purpose of using the rotary evaporator?

What is the purpose of using the rotary evaporator?

The rotary evaporator can seal and reduce pressure to 400-600 MMHG. The solvent in the evaporation flask is heated with a heating bath. The heating temperature can be close to the boiling point of the solvent, at the same time, rotating the evaporation flask, the rotating speed could keep at 50-160rpm/min, make the solvent being thin film, increase evaporation area.
