The rotary evaporator uses a rotating flask, which is placed in a water bath and heated while rotating to promote diffusion and evaporation of the solution in the bottle. Under vacuum, the material will form a large-area film on the bottle wall to expand the evaporation area, and then undergo cooling. The condenser is cooled and then collected into a collection bottle. It can be used in pilot experiments in the fields of biology, medicine, chemical industry, food, etc., and also plays a big role in the processing of high-value samples. It forms a supporting device with a diaphragm vacuum pump, a circulating cooler, etc.
