Rotovap Distillation: What Is A Rotary Evaporator? - BVV

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.

Rotary Evaporators & Rotovaps [New Guide in 2022]

A rotary evaporator (or rotavap or rotovap) uses precise engineering to effectively remove solvents from a sample using evaporation. Most rotovaps make use of a vacuum and pressure control monitor to precisely control pressure within your system, increasing evaporation efficiency. In many commercial labs, these machines need to be running

ORGANIC LABORATORY TECHNIQUES 8 8.1 ROTARY …

The rotovap works by increasing the rate of evaporation of the solvent by (1) reducing the pressure to lower the solvent boiling point, (2) rotating the sample to increase the effective surface area and (3) heating the solution. To use the rotovap, first make sure that the power is on (top right of the stand).
