How to install Dual condenser Rotary Vacuum Evaporators with dual receiving flask?

With the rapid development of technology, more and more effective devices are invented to facilitate experiment processes in chemical labs. Rotary vacuum evaporator is one of them, which is a device used to extract solvents from sample with high efficiency through evaporation. For getting a higher efficiency, there are several essential parts in the whole rotary vacuum evaporator equipment.

  01.Vacuum Pump

Vacuum pump provides a partial vacuum environment for the whole equipment, which creates a pressure difference between the sealed equipment and ambient pressure. One the one hand, the pressure difference forms a continuous feed system, which can help to draw into sample without stopping the operation. On the other hand, vacuum environment prevents extracted solvents reacting with oxygen or other ingredients from air to get pure solvents.

  02. Evaporation flask

In the whole process, evaporation flask will keep rotating in a constant speed, in order to facilitate evaporation by enlarging evaporation area.

  03. Chiller and condenser

Chiller and condenser match with each other to condense extracted solvents which later go into receiving flask from gas to liquid.

Besides vacuum pump、chiller 、condenser and evaporation flask, there are also some other essential parts. For example,vacuum gauge、water or oil bath、high-quality stainless steel main rack、integral control panel、receiving flask、connection bottle with PTFE sealing valve.

  Advantages of Rotary vacuum evaporator:

01. The purity of extracted solvents are totally guaranteed because the sealed equipment are under vacuum. And there won’t be any other chemical substance having chemical reaction with extracted solvents.

02. The frame is made of stainless steel so it’s absolutely firm enough to support the whole equipment. And stainless steel makes the whole equipment look neat. Besides, the receiving flask and evaporation flask is made of high borosilicate glass which looks very clear.

03. Users can adjust the speed of evaporation flask、the height and temperature of water or oil bath by integral control panel.
