Rotary Evaporation - Chemistry LibreTexts

Rotary Evaporation - Chemistry LibreTexts

Aug 15, 2021 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 are Rotary Evaporators and How Do They Work?

Feb 25, 2021 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.

How rotary evaporator works? Explained by FAQ Blog

May 30, 2022 A typical rotary evaporator has a water bath that can be heated in either a metal container or crystallization dish. This keeps the solvent from freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser and is collected for easy reuse or disposal.

The water bath temperature should not exceed the boiling point of the solvent! • The condenser could be overloaded since the evaporation rate will exceed the condensation capacity. Cannabis extracts require lower water bath temperatures (≈40 degrees Celsius). Oil baths can hold a higher temperature range than water baths.
