How Does The Rotovap Lower The Boiling Temperature

Apr 04, 2019 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.
