Influence on evaporation efficiency of rotary evaporator.

Aug. 19. 2022

The efficiency of the rotary evaporator determines the number of distilled samples. Under the same solvent, the higher the evaporation efficiency, the more samples will be obtained.

Influence on evaporation efficiency of rotary evaporator.

1. The high or low temperature of circulating liquid will have a great impact on the condensing efficiency of the condenser. The high temperature of circulating liquid will reduce the condensing efficiency, and the steam cannot be condensed and stored in the equipment in time, resulting in insufficient vacuum, thus affecting the evaporation efficiency.


2. The higher the temperature in the bath, the faster the evaporation rate of the experimental solvent in the rotary flask.


3. The vacuum value will also have a certain impact on the condensing efficiency. The vacuum pump, sealing ring and vacuum pipe will have an impact on the vacuum value. Vacuum controller and vacuum valve can be installed as required to better control the vacuum value of the rotary evaporator.


4. The faster the rotation speed of the rotary flask, the larger and thicker the film formed by the solvent in the bottle on the bottle wall, and the larger the heated evaporation area, the higher the evaporation efficiency.
