Wide Application: A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. The water circulating wacuum pump is used to provide vacuum condition for the process of evaporation, distillation, crystallization, drying, sublimation, filtration. Rotary Evaporator can be rotated under constant temperature heating and under negative pressure to form a film, evaporate efficiently, and then condense and recover the solvent. It is especially suitable for the concentration, crystallization, separation and solvent recovery of heat sensitive materials. Some models can also be used for reflux extraction. It is one of the basic instruments necessary for the chemical industry, pharmaceutical industry, universities and research laboratories. And the main means of extracting and concentrating in the analysis experiment.
