Zhengzhou Greatwall Scientific Industrial And Trade Co., Ltd.

Working Principle <br />
 <br />
     50L Explosion-proof Rotary Evaporators are used for purification and distillation test. They rotate and shape a thin film in negative pressure condition by heating, evaporate efficiently, and then condense and recollect solvent to purify and separete.<br />
 <br />
Application <br />
 <br />
1. An ( explosion-proof ) rotary vacuum evaporator (or rotavapor) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.<br />
 <br />
2. ( Explosion-proof ) rotary vacuum evaporators can be used with recirculating water multi-use vacuum pump and cooling liquid circulating pump/ recirculating cooler to form the total system.<br />
