Rotary evaporators can be divided into mini rotary evaporator and large scale rotary evaporator according to the capacity of the rotating bottle. The common types of mini rotary evaporators are 2l rotary evaporator and 5l rotary evaporator, and the large ones are usually 10l rotary evaporator and 50l rotary evaporator.
Main use of rotary evaporator：
1.Separating liquid mixture.
2.Purification, by purifying the substance containing a small amount of impurities, improving its purity.
3.Recover solvent or evaporate part of solvent to concentrate solution.
4.Evaporation, concentration, crystallization, drying, separation, solvent recovery.
Factors affecting the evaporation rate of the rotary evaporator:
1.Water bath temperature.
2.Vacuum in the rotary evaporator.
3.Is the condensing recovery unit highly efficient?
4.Rotating speed of the rotating bottle.
