[0002] Rotary evaporator, also known as rotary evaporator, is a common laboratory equipment, composed of motor, distillation flask, heating pot, condenser and other parts. It is mainly used for continuous distillation of volatile solvents under reduced pressure conditions. It is used in chemistry, chemical industry, biomedicine and other fields. 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, it is unnecessary to add zeolite and there will be no violent boiling. At the same time, due to the continuous rotation, the liquid adheres to the wall of the distiller to form a layer of liquid film, which increases the evaporation area and speeds up the evaporation rate.
