TOPTION rotary evaporator is the most commonly used evaporator in the laboratory for concentration, alcohol
recovery, and solvent removal. Here we mainly look at the application of the rotary vacuum evaporator in the
recovery and evaporation of organic solvents.
The roto evaporator uses a motor to drive the evaporation flask to rotate. Since the evaporator is continuously
rotating, the zeolite can be added without boiling. At the same time, due to continuous rotation, the liquid adheres
to the wall of the evaporation flask to form a layer of liquid film, which will increases the evaporation area & speeds
up the evaporation efficient. Note when using
1. In the vacuum evaporation distillation process, when the temperature is high and the vacuum is low, the liquid
in the evaporation bottle may suddenly boil. At this time, the degree of vacuum should be lowered so that the
distillation process can proceed smoothly ( vacuum controller is optional).
2. When stopping rotary evaporation, first please stop heating, then stop vacuuming, finally cut off the power to
