How rotary evaporator works

The working process of rotary evaporator is a consecutive process under a reduced environment. There are several steps here:

1. Under reduced pressure, the evaporation flask was continuously rotated while the solvent was being distilled. The evaporation flask is a pear-shaped or round-bottomed flask with a standard ground mouth connection. It is connected with the pressure reduction pump through a serpentine condenser.

2. After substances get evaporated by heating, the gas-phase substances will go into condensing part to get condensed. In this step, gas substances are transferred through the glass tubes.

3. After gas-phase substances got condensed into liquid-phase, the liquid-phase substances will be transferred into receiving flask, which is the final destination of extracted substances. And then users will take the receiving flask out of rotary evaporator equipment.

During the whole working process, there is always a vacuum pump providing a vacuum environment for the rotary evaporator equipment. A vacuum environment guarantees the whole system work in a reduced environment and the automatic feeding system formed by the pressure difference between atmosphere pressure and vacuum pressure.

Can rotary evaporator remove water

Rotary evaporator is widely used in removing water from materials, which is to concentrate substances. Removing water by rotary evaporator is commonly used in kitchen, for example, concentrate fruit juice, which is to remove water from fruit juice. Besides, there are other examples of removing water from substances.
