There are four parts in the whole rotary evaporator equipment – condensing part、evaporation part、vacuum pump、receiving part. Each of them is in charge of different work. Following are the parts of rotary evaporator and their functions :
1. In the evaporation part, evaporation flask rotates in a constant speed to facilitate evaporation by enlarging evaporation area.
2. Vacuum pump removes gas from the sealed equipment to leave behind a partial vacuum, in order to create a continuous feed system and keep the purity of extracted solvents.
3. Condensing part cools the equipment and turns extracted solvents from gas into liquid.
4. Then the solvents liquid goes into receiving flask for users to get.
