A rotary evaporator is a device commonly used in chemical laboratories for the efficient and gentle removal of the volatile solvents from samples by evaporation. They are found in almost every organic laboratory. The rotation flask rotates and shapes a thin film in negative pressure condition by heating; it evaporates; and then the vapor is condensed, liquefied, and recollected for separation.
A typical thin film evaporator has a water bath that can be heated in either a metal container or crystallization dish. This keeps the solvent from freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser, and is collected for easy reuse or disposal.
Rotary evaporators are distillation units that incorporate an efficient condenser with a rotary flask system. As the flask containing the solvent is rotated it continually transfers a thin layer of liquid over the entire inner surface. This gives a very large surface area for evaporation that is effected by heating from the accessory water or oil bath.

Low temperature cooling liquid circulating pump
- Rotary evaporator matching use with circulating water vacuum pump to offer a vacuum environment for reduced pressure distillation, they are widely used for vacuum filtration, vacuum evaporation, vacuum degassing, etc..
- Rotary evaporator matching use with GDSZ series high and low temperature circulating pump to quickly cooling or warming, the circulating pump is an efficient equipment for quick temperature adjustment.
- Rotary evaporator matching use with DLSB series low temperature cooling liquid circulating pump to conduct chemical reaction and medicine storage which requires low temperature environment.
Features of rotary evaporator
- Highly Chemical Resistance-All components that make contact with liquids and gases are made of borosilicate glass 3.3 and PTFE.
- Specialized motor with extremely compact, intermeshed worm and worm gear provides precise driving for very quiet, vibration-free operation.
- Downward-condensing vacuum connection design ensures safe vacuum operation
- Modular design (individual rotary and water bath modules) for extremely easy maintenance and easy future upgrades
- Easy auto lift with secure lock for the evaporating flask
- Easy, straight-forward and visual operation with digital speed and temperature display
