RotoVap vs Falling Film Evaporation - TruSteel LLC

Dec 09, 2019 For years, the industry standard for solvent recovery has been the rotary evaporator, or otherwise known as the RotoVap. A generic 20L RotoVap has a recovery rate of about 1.5 gallons per hour. For small-scale setups, this may suffice, but large-scale manufacturers have been forced to run multiple RotoVaps.

Rotovap Distillation: What Is A Rotary Evaporator?

Jul 21, 2017 Yes: a cold trap is always recommended when using a rotovap. Because ethanol is an alcohol, it’s very difficult to re-condense. Some ethanol vapor will pass through the condenser during evaporation. A cold trap is needed to capture the vapor before it reaches the vacuum system. This considerably prolongs the lifespan of the vacuum pump.
