The 1l rotary evaporator is mainly used to continuously distill a large amount of volatile solvents under reduced pressure, such as distillation extract and receiving liquid during chromatographic separation.

　　1.There are two external joints on the condenser for connecting the cooling water. One end is for water inlet, and the other for water outlet. The lower the condensate temperature is, the better the condensation effect is. A vacuum connector is installed on the upper port, which can connect a vacuum pump hose for vacuumizing.

　　2.In use, reduce the pressure first and then start the motor to rotate the distillation flask. After use, stop the motor first and then ventilate to prevent the distillation flask from falling off during the rotation.
