The vacuum distillation reactor is a device that quickly concentrates or separates the liquid medium. The reaction medium is heated to the boiling point in the reactor, and the stirring system is continuously rotated to increase the evaporation surface area and accelerate the evaporation speed. Appropriate vacuum conditions can achieve The boiling point of the medium is quickly separated, condensed by the condenser and collected.

The stirring system of Zhengwei experimental kettle adopts magnetic stirring and static sealing, which can maintain a high degree of vacuum. The device is mainly used for concentration, crystallization, drying, separation and solvent recovery in the pharmaceutical, chemical and biopharmaceutical industries.
