Rotary Evaporators - Across International

Rotary Evaporators - Across International

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

Dec 28, 2000 · Evaporator economy can be increased by increasing the number of effects. A multiple effect system (Fig 2) uses the vapor from the first effect as the steam source for each subsequent effect. As the temperature decreases in each succeeding stage, evaporation continues because the pressure and boiling point also are reduced.

Evaporator - an overview | ScienceDirect Topics

A vacuum evaporator used to work by bringing down the pressure over a mass of fluid, thus reducing the boiling points. The rotary evaporator works by increasing the rate of evaporation of the solvent by: reducing the pressure to lower the solvent boiling point, rotating the sample to increase the effective surface area, and heating the solution.

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.
