A vacuum rotary evaporator is used for quick single-stage distillations that treat the product gently. The process is based on the evaporation and condensation of solvents in a rotating evaporating flask. It is possible to work under a vacuum to ensure gentler treat-ment of the product and increase productive output.

How Rotary Evaporator How It 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).

The fins are added to the bare-tube to increase the heat transfer capability. They act as heat collector that pick up heat from the surrounding air and conduct it to the refrigerant inside the tube hence improving the efficiency in cooling the air of the surrounding. They are best used in the air-cooling space where the temperature is around 34F.
