Ethanol/Alcohol recovery, Solvent remove, Evaporation, Concentration, Separation, Crystallization, Drying, are the most common application field of rotary evaporator.
Ethanol/Alcohol recovery, Solvent remove, Evaporation, Concentration, Separation, Crystallization, Drying, are the most common application field of rotary evaporator. Because of its wide capacity range ( 1L, 2L, 3L, 5L, 10L, 20L, 30L, 50L, 100L ) and economical price, vacuum rotary evaporator has become the most ideal and most selected evaporation equipment in the fields of chemistry, pharmaceutical industry, essential oil extraction industry, food industry, whiskey purification, home laboratory and other fields.
The working principle of the rotary evaporator is very simple, the liquid material is added to the rotating bottle, heated by the water / oil bath, while the rotating flask is driven by the motor to rotate at a uniform speed, the liquid forms a thin film in the rotating bottle, and steam is formed under the condition of uniform heating. The steam meets at the position of the condenser, be cold and condensed to form a liquid collected in the collection bottle. The whole process separates and concentrates through the different boiling points of the materials.
Therefore, many customers choose to use rotary vacuum evaporator together with a chiller and a vacuum pump. After connecting the vacuum pump, the boiling point of the material under the vacuum system will be reduced, thereby improving the overall work efficiency. Connecting chiller can enhance the efficiency of condensation, thereby improving the efficiency of the entire solvent recovery. Of course, for small experimental rotary evaporators, you can also choose to connect cold water for condensation.
