Rotary Evaporator Principle | PDF | Distillation

Principle of operation of Rotary evaporators A rotary evaporator is an instrument used to evaporate solvents under vacuum with the use of rotation and heat. The vacuum is used to lower the boiling temperature thus minimising damage to thermolabile substances. Rotation is used to distribute the liquid as a thin film over the flask surface thus increasing the surface area for …

Rotary Evaporator Working Principle. 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.
