Why Do We Use Rotary Evaporator? - WKIE LAB.com

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).

What is the purpose of using the rotary evaporator?

What is the purpose of using the rotary evaporator?

A rotary evaporator allows for a precise and gentle distillation conventional machines cannot provide. The main reason why rotary evaporators are better than traditional devices is that it removes the solvent under vacuum. Vacuum lowers the boiling point, therefore eliminating the need for high temperature for the distillation process to occur.
