Rotary Evaporator - Built For Visionaries

A rotary evaporator, or rotavap, is a piece of equipment that efficiently and gently removes volatile solvents from your product through evaporation. The main components of a rotavap are: An evaporation flask, which contains the sample material. A motor that rotates the flask. A vacuum-sealed vapor pathway, which draws vapor off the sample.

How to Select a Vacuum Pump for Rotary Evaporation?

Applying vacuum using a pump is either helpful or necessary in most rotovap applications as it reduces the pressure within the system. This lowers the boiling temperature of the solvent resulting in faster evaporation and safer rotary evaporator operation. When composing a rotary evaporator setup, not just any pump will be up to the task.

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.

Controlling the vacuum also reduces the build-up of oscillation and improves solvent recovery and reproducibility. Manual vacuum control uses a stopcock or a manual valve and the vacuum level is adjusted by sight. With this method, the whole process must be closely monitored as the level of vacuum required can change during evaporation.
