How does rotary evaporation work? - Lab Instrument Manufacturer

A rotary evaporation (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 ...

How to Select a Vacuum Pump for Rotary Evaporation?

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.
