The structure of the rotary evaporator is very simple. It is mainly composed of rotating motor, oil bath, rotating flask condenser, collecting bottle, etc. Generally, in order to improve work efficiency, many customers will choose to match the vacuum pump and chiller. The following figure is a simple structure diagram and pictures of vacuum pump and chiller. I hope to bring you reference.
The principle of rotary evaporator is also very simple, that is, under the vacuum conditions, constant temperature heating makes the evaporation bottle rotate at a constant speed, and the material forms a large-area film on the wall of the evaporating flask, so as to evaporate efficiently. The steam rises, is cooled by a glass condenser (cooling water bath is optional), and is finally recycled into the collection bottle to achieve the purpose of solvent removal, alcohol recovery, concentration, crystallization, drying and separation.
