A rotary evaporator (or rotavap/rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.
Rotary evaporators are also used in molecular cooking for the preparation of distillates and extracts.
The main components of a rotary evaporator are:
1. A motor unit that rotates the evaporation flask or vial containing the user's sample.
2. A vapor duct that is the axis for sample rotation, and is a vacuum-tight conduit for the vapor being drawn off the sample.
3. A vacuum system, to substantially reduce the pressure within the evaporator system.
4. A heated fluid bath (generally water) to heat the sample.
5. A condenser with either a coil passing coolant, or a "cold finger" into which coolant mixtures such as dry ice and acetone are placed.
6. A condensate-collecting flask at the bottom of the condenser, to catch the distilling solvent after it re-condenses.
7. A mechanical or motorized mechanism to quickly lift the evaporation flask from the heating bath.

Rotary evaporator’s working principle is to rotate the glass flask which filled with materials under constant temperature heating, and the system connect to the negative pressure to low the boiling point, then liquid forms a film and evaporates,at last it recovers the menstruum by the glass coil condenser and receiving flask. It is specially applicable for the concentration, crystallization, separation and menstruum recovery of heat sensitive materials.
