Rotary Evaporator - ChemBAM

Rotary Evaporator - ChemBAM

A rotary evaporator (sometimes abbreviated to rotavap) is a piece of equipment primarily used to remove solvent from a sample through “evaporation under reduced pressure”. The presence of reduced pressure in the apparatus causes the solvent (in the round bottom flask) to boil at a lower temperature than normal.

How We can Use Rotary Evaporator for Extraction? - Rotovap

Mar 02, 2020 The answer is “YES”. A rotary evaporator can remove solvent by evaporating samples through the continuous rotation of the evaporation flask. Meanwhile, the evaporation flask is heated uniformly by a water bath. Then the material with a lower boiling point can be evaporated quickly under negative pressure.

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. Why are rotary evaporators better?

May 30, 2022 Why are rotary evaporators better? Removal of solvent by a rotary evaporator is superior to evaporation under atmospheric pressure for many reasons. The process is much quicker (often takes less than 5 minutes), uses lower temperatures (so decomposition is unlikely), and uses less energy than boiling with a heat source.
