How Rotovap Is Used

A rotovap is a device used in manufacturing laboratories for efficient and sensitive solvent removal from evaporation tests.. It is found in almost all natural laboratories because it allows you to do the job quickly. The medium rotary evaporator contains a water shower that may be heated in a metal container or crystallization dish.

How does rotary evaporation work? -

How does the rotary evaporator work? The rotovap works by increasing the rate of evaporation of the solvent by (1) reducing the pressure to lower the solvent boiling point, (2) rotating the sample to increase the effective surface area and (3) heating the solution. To use the rotovap, first make sure that the power is on (top right of the stand).
