Glass reactors are ideal equipment for modern chemical sample experiments, biopharmaceuticals and new material synthesis. They are widely used in laboratories. We have talked about the classification and selection of reactors. Let's take a closer look at the following issues:

1. What is the general working principle of the glass reactor?

The glass reactor is stirred and reacted under normal pressure or negative pressure in a closed container under the set constant temperature, and the evaporation and reflux of the reaction solution can be controlled. Generally, there are single-layer glass reactors and double-layer glass reactors. (Supplementary Note: Installation Precautions for Glass Reactor)

2. What are the uses of the single-layer glass reactor and what is its working principle?

The single-layer glass reactor can provide high temperature reaction (the maximum temperature can reach 300℃); it can also be evacuated to do negative pressure reaction. The single-layer glass reactor can carry out various solvent synthesis reactions under constant temperature conditions. The reaction part of the instrument is a controllable and fully sealed structure. It can continuously inhale various liquids and gases by using negative pressure, and can also do reflux or distillation at different temperatures.

The working principle of the single-layer glass reactor is that the reactor body is directly heated by the silver film heating plate, so that the materials in the reactor can be heated at a constant temperature, and stirring can be provided. The materials are reacted in the reactor, and the evaporation and reflux of the reaction solution can be controlled. After the reaction is completed, the lid and motor part of the single-layer glass reaction kettle are mechanically lifted (electric lifting is optional), and the kettle body can be rotated 360 degrees to facilitate material dumping and discharging, and the operation is extremely convenient. It is an ideal equipment for modern chemical sample, medium sample experiment, biopharmaceutical and new material synthesis.

3. What are the uses of the double-layer glass reactor and what is its working principle?

The interlayer of the double-layer glass reactor can be used for high-temperature reaction (the maximum temperature can reach 300℃), and it can also be used for low-temperature reaction (the temperature can reach -80℃); the double-layer glass reactor can be evacuated for negative pressure reaction. The double-layer glass reactor can carry out stirring reaction at room temperature, high temperature reaction, negative pressure vacuum distillation reaction, separation and extraction, distillation reflux reaction, and concentration reaction.



The double-layer glass reactor is designed with double-layer glass. Its working principle is: put the reaction solvent in the inner layer of the glass for stirring reaction, and the interlayer can be connected to different cold and heat sources (refrigerated liquid, hot water or hot oil) for circulation Heat or cool the reaction. Through the interlayer of the double-layer reactor, a constant temperature (high temperature or low temperature) hot melt medium or cooling medium is injected to heat or cool the materials in the reactor at a constant temperature. At the same time, the stirring reaction can be carried out under normal pressure or negative pressure according to the requirements of use. The material is reacted in the reaction kettle, and the evaporation and reflux of the reaction solution can be controlled. After the reaction is completed, the material can be discharged from the discharge port at the bottom of the kettle, and the operation is extremely convenient.
