Rotary Evaporators Rotovaps [New Guide in 2022]

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 ...

Nov 25, 2016 Remember, when the condenser on your evaporator is 20 degrees Celsius cooler than your sample, it will condense most of the vapors leaving the evaporator. That means that a small pump with modest pumping capacity – 1 cfm or less – will provide enough pumping to manage the residual vapors that reach the pump from most benchtop evaporators.
