Rotatory Evaporator Working Principle - Rotary …

Rotatory Evaporator Working Principle - Rotary …

The rotatory evaporator working principle is that the boiling point of liquids lowers on decreasing their pressure. This allows the solvent to vaporize at lower temperatures than when boiled in a normal atmosphere. You should choose a vacuum pump for your rotavap that will guarantee an improved evaporation efficiency.
