Rotary evaporator is a commonly used equipment in the laboratory. It consists of a motor, a distillation flask, a heating pot, a condenser, etc. It is mainly used for continuous distillation of volatile solvents under reduced pressure, and is used in chemistry, chemical engineering, biomedicine and other fields.

The rotary evaporator can be used to recover and evaporate organic solvents. It uses a motor to drive the distillation flask to rotate. Since the distiller is constantly rotating, the zeolite can be eliminated without bumping. At the same time, due to the continuous rotation, the liquid is attached to the wall of the distiller, forming a layer of liquid film, which enlarges the evaporation area and accelerates the evaporation speed.
