How to Select a Vacuum Pump for Rotary Evaporation?

Applying vacuum using a pump is either helpful or necessary in most rotovap appliions 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.

Rotary evaporator vs short path distillation
