3/27/2020· 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.

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).

6.8.2.1 Rotary Vacuum Evaporator. The Rotary evaporator is a common laboratory apparatus used for quick removal of solvents from reaction mixtures. This is done by heating mixtures gently under reduced pressures to accelerate the rate of evaporation. A vacuum evaporator used to work by bringing down the pressure over a mass of fluid, thus reducing ...
Chat Online2/27/2019· Working Principle of a Rotary Evaporator A rotary evaporator (rotovap or rotavap) evaporates solvents from samples by utilizing the principle that the solvent will have a lower boiling point at a reduced pressure. Specifically speaking, the stepless speed regulation is adopted to make the evaporation flask rotate at a constant speed.
