Rotary Evaporation - Chemistry LibreTexts

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 .

What is the purpose of using the rotary evaporator? - Lab .

A rotary evaporator (or rotavap/rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.. The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid).

The "Golden Rule" for Solvent Removal

remember for solvent removal via rotary evaporation is the 20/40/60 Rule. These numbers refer to the D20ºC principle. Since Buchi invented the Rotary Evaporator 50 years ago, Buchi has continued to make advancements to the Rotavap as well as vacuum pumps and controllers. The newest controllers from Buchi feature not only a large
