What are Rotary Evaporators and How Do They Work?

Feb 25, 2021 What is Rotary Evaporation? Evaporation is a gentle, efficient way to remove solvents and the process of rotary evaporation is a reduced-pressure distillation. It involves placing a sample within a round-bottomed flask, which is then placed in the rotovap’s heated water bath and rotated. A vacuum pump reduces the pressure above the solvent.

Jun 22, 2020 Rotary evaporation is the process of reducing the volume of a solvent by distributing it as a thin film across the interior of a vessel at elevated temperature and reduced pressure. This promotes the rapid removal of excess solvent from less volatile samples. Most rotary evaporators have four major components: heat bath, rotor, condenser, and ...

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.

Rotary Evaporation - an overview ScienceDirect Topics

Rotary evaporation: Solvent is removed at reduced pressure by mechanically rotating a flask in a controlled temperature water bath. Condensed solvent is collected in a separate flask: Volatile compounds are typically lost. Recovery of less volatile material may be lower than expected due to entrainment of the analyte the solvent vapor.
