An Automatic Rotary Evaporator is a laboratory instrument used for efficiently and gently removing solvents from samples by evaporation. It works by rotating a flask containing the sample under controlled heat, creating a thin film of the sample inside the flask. The rotation increases the surface area for evaporation. The evaporator uses vacuum pressure to lower the boiling point of solvents, making the process faster and more energy-efficient.

Working Principle : A rotary evaporator is a device used in Chemical Laboratories for efficient and gentle removal of solvents from samples by evaporation.

The main components of a rotary evaporator are :
1. Motor unit which rotates the evaporation flask containing sample material.
2. A vapour duct which acts as axis for sample rotation, and a vacuum tight conduit for the vapour being drawn off of the sample.
3. A vacuum system (not integral part of the equipment) to substantially reduce the pressure within the vaporator system.
4. A heated fluid (water / thermic fluid) bath to heat the sample being evaporated.
5. A condenser with double coil through which the coolant passes.
6. A condensate collecting flask at the bottom of the condenser, to collect the distilling solvent after it recondenses.
7. A mechanical or motorized mechanism to quickly lift the evaporation flask from the heating bath or lowerthe heating bath so that the evaporation flask does not remain in contact with bath.


The vacuum evaporators as a class function because lowering the pressure lowers the Boiling Points of component liquids in it. Generally the component liquids of interest in applications of rotary evaporation are solvents that one desires to remove from  a sample after an extraction, for instance , following a natural product isolation or a step in an organicsynthesis . Use of a Rota – Evaporator therefore allows liquid solvents to be removed without excessive heating of what are often complex and sensitive solvent – solute combinations.
