Rotary evaporator parts and function

  Parts of rotary evaporator and their functions

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.in this part, there is a heating mantle to heat materials in the evaporation flask, and get materials evaporated. What’s more, the evaporation flask will keep rotating in a constant speed to get a bigger evaporation area, in order to get materials evaporated more quickly.

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.it provides the rotary evaporator equipment a vacuum environment. This vacuum environment has two functions: firstly rotary evaporator needs a reduced pressure environment; secondly, the pressure difference between a vacuum environment and atmosphere pressure creates a automatic feeding system.

3. Condensing part cools the equipment and turns extracted solvents from gas into liquid.in this part, the gas-phase materials can get condensed by condensing tubes, and then they will be turned into liquid-phase materials. After condensing materials, it is more convenient to collect materials for users.

4. Then the solvents liquid goes into receiving flask for users to get.this part is about the final step of working process. In this part, the liquid-phase materials will be transferred and collected here. And then the users will take the receiving flask very easily.

These four parts are the main parts of rotary evaporator equipment. Besides these four parts, there are still some tiny accessories, such as iron holder and valve.

  How does a rotary evaporator work?

Rotary evaporator is used to extract solvents from liquid mixtures by evaporation in chemical、biochemical and other fields. At first, samples are placed in evaporation flask. With the evaporation flask rotating in a constant speed, there will be a thin film of sample inside evaporation flask, which facilitates evaporation. Then extracted solvents are transferred into condenser and condensed into liquid from gas. This whole process is taking place in a partial vacuum created by vacuum pump.

  Rotary evaporator with chiller and other accessories

In the process of evaporation, condensing solvents from gas into liquid is very important for users to get solvents. Chiller is in charge of cooling the equipment to turn gas solvents into liquid solvents. Besides chiller, there are still some other essential accessories in the rotary evaporator equipment. For example, vacuum pump leaves behind a vacuum for the whole equipment in order to create a continuous feed system.

  Rotary evaporator principle

Rotary evaporator working principle is mainly about two aspects(beginning and ending): firstly, removing gas from the sealed equipment to get a partial vacuum before rotating the evaporation flask to prevent evaporation flask falling down. Secondly, stopping the rotation before stopping vacuum pump to prevent evaporation flask falling down or suck-back.
