Rotary Evaporation

Rotary Evaporation

A major advance in efficiency is achieved by using a rotary evaporator (rotovap). This cuts the distillation time for eliminating ether from a couple of hours down to 20 minutes or so. The basic theory is that the apparatus works by vacuum distillation. Rotating the pot (on the left in the picture) provides agitation, maintains contact with ...

Apr 07, 2015 A rotovap typically uses a cold condenser to condense the solvent into a collection flask. But the distillation is typically done under weak vacuum as well. So the solvent sitting in the collection flask seem susceptible to re-vaporizing and getting sucked into the vacuum pump.

Sep 19, 2017 Depending on the model a rotovap may have a built-in vacuum control and only a vacuum pump needs to be added. If this is not the case, however, you will probably need both a vacuum pump and a manual or digital vacuum controller. A controller can significantly increase your cost, check out this blog for advice on minimizing this.
