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).
