Rotary Evaporator is essentially a thin film evaporator also called rotary vacuum evaporator. These features combined, renders rotary film evaporator to be ideally suited for evaporation of heat sensitive material. It is equally successful for evaporation of suspension in crystallization processes, drying of powder / granules etc.

The main components of a rotary evaporator are: * A motor unit that rotates the evaporation flask or vial containing the user's sample.
* A vapor duct that is the axis for sample rotation, and is a vacuum-tight conduit for the vapor being drawn off the sample.
* A vacuum system, to substantially reduce the pressure within the evaporator system.
* A heated fluid bath (generally water) to heat the sample.
* A condenser with either a coil passing coolant, or a "cold finger" into which coolant mixtures such as dry ice and acetone are placed.
* A condensate-collecting flask at the bottom of the condenser, to catch the distilling solvent after it re-condenses.
* A mechanical or motorized mechanism to quickly lift the evaporation flask from the heating bath.
