How to use a Rotary Evaporator

Apr 01, 2010 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. ... (see table below). Solvent: b.p. (760 torr) b.p ...

Selecting a Suitable Vacuum Pump for Your Rotary Evaporator

Apr 04, 2019 Ideally, a pump used in a rotovap setup should be oilless and chemical-resistant to make sure it lasts as long as possible. The most commonly used pumps for this purpose are diaphragm (or membrane displacement) pumps. A variety of pumps (from left to right): an ME1 Diaphragm Pump, a VP Series Vacuum Pump, and a MVP 10 basic Vacuum pump.

Jun 05, 2019 Rotary evaporation works by the mechanical rotation of a flask to increase the surface area of the solvent, which quickens the rate of evaporation and improves efficiency. This rotation is done under a vacuum, which reduces the solvent’s boiling point and helps remove the solvent from less-volatile samples.

Mar 01, 2021 To begin the process of rotary evaporation, a solvent is placed in a round-bottomed flask in the water bath of the rotary evaporator system. The system’s pressure is then reduced below atmospheric pressure through the use of a vacuum pump. Reducing the pressure in the rotary evaporator has numerous benefits. Namely, the reduced pressure ...
