What is a glass reactor？

For some customers who are new to 50l jacketed glass reactor, they may wonder what glass reactors are used for, so today, I will briefly explain what glass reactors are for my friends on Zhihu. And the method of using the glass reactor. I hope this article can dispel your doubts and let you understand the purpose of glass reactors.

 

The 100l reactor is actually just one of many reactors. Other laboratory jacketed glass reactors include glass-lined reactors, hydrothermal synthesis reactors, magnetic stirring reactors, electric heating reactors and steam reactors. But glass reactors are the most commonly used. The glass reactor has the characteristics of no pollution, high temperature resistance, corrosion resistance, sanitation, and fast heating speed.
 
The basic working principle of thelaboratory jacketed glass reactor is to stir the reaction in a closed container with a set constant temperature under normal pressure or negative pressure, and control the reflux and evaporation of the solution. There are single-layer glass reactors, double-layer glass reactors and triple-layer glass reactors.
 
The most common of these is the laboratory jacketed glass reactor. The application of the double-layer glass reactor can be summarized as: high temperature reaction (the highest temperature can reach 300), low temperature reaction (the lowest temperature can reach -80), vacuum reaction, constant temperature solvent synthesis reaction, distillation reflux reaction, vacuum distillation reaction, separation and extraction reaction, purification reaction, concentration reaction, stirring reaction, etc. According to different use conditions and requirements, users can adjust the use temperature and pressure to adapt to different experimental environments.
 
As a biochemical instrument, the laboratory jacketed glass reactor is widely used in industry, so it is widely used in modern fine chemicals, scientific research experiments, biopharmaceuticals, colleges and universities, etc. It is an ideal equipment for teaching, experiment, production and pilot test.
 

Glass Reactor Features：

The laboratory jacketed glass reactor adopts a double-layer glass reactor, which can really realize the multi-purpose of the experiment and meet the needs of all aspects of different experiments. This equipment can carry out:
1. Vacuum stirring reaction
 
2. High temperature, low temperature reaction
 
3. Constant speed running and mixing reaction
 
4. Can be distilled, refluxed, concentrated
 
5. Negative pressure operation, liquid dispensing function
 
6. Rectification by assembling a rectification column
 
7. Assemble into laboratory jacketed glass reactor production line according to specific requirements.
 
8. For plant extraction, concentration has a good process effect
 
9. Stirring and separation, equipped with liquid separation device, the effect is obvious
 
10. Carry out the reaction production of ultra-fine powder, and make medicines at a sanitary level, which can be seen and clean.
 
11. It can replace the rotary evaporator to concentrate high-purity materials, configure ultrasonic stirring, and reduce the reaction time exponentially.
 
12. No matter separation or synthesis, the feeding is convenient and the operation is simple.
 
Combination series laboratory jacketed glass reactor, double glass reactor, is a new applications of glass reactor based on the single-layer multifunctional laboratory jacketed glass reactor after years of improvement, which realizes convenient high and low temperature, as well as rapid heating and cooling. It is an ideal instrument for modern laboratory, chemical, pharmaceutical, and new material synthesis.
 

Precautions for the use of glass reactors：

When using a laboratory jacketed glass reactor, heating or cooling should be done slowly. When steam heating, 0.1Mpa steam should be kept in the jacket for 15 minutes before boosting, until the boosting pressure reaches the operating pressure value, but it should not exceed the design pressure value.
 
When adding materials to the glass reactor, please be careful not to exceed the nominal capacity, and do not add a small amount of material or empty the tank for heating. When materials enter the equipment, be careful not to trap lumps of metal and garbage, and crush large pieces of hard materials before entering.
 
Minimize the temperature difference between the material and the tank wall, avoid cold tank heating materials and hot tank heating materials The lubricating fluid in the mechanical seal chamber should be clean and free of solid particles.
 
The maintenance of the applications of glass reactor mainly includes: When maintaining the glass reactor, if it is found that the heat dissipation of the equipment is insufficient, it means that there is a problem. Check whether the condenser is consistent with the host. If it is inconsistent, it should be dealt with immediately.
 
In addition, the fins of the condenser can also be washed with water, but cannot be used for a long time. Over time, the fins of the condenser are prone to scale, which will affect the heat transfer capacity and effect.
 
The finned tubes of the applications of glass reactor must be cleaned and arranged to ensure that they are clean and tidy.

 

Buying Guide for Glass Reactors!

1. Have a basic understanding of the product
Different applications of glass reactor have different characteristics. First, a brief introduction to single-layer and double-layer glass reactors. Single-layer glass reactor, stirring speed is 0-600rpm. The stirring power is 120w1/3, and the heating power is 3kw. Double-layer glass reaction kettle, stirring speed is 0-600rpm. The stirring power is 120w1/3, and the frame material is stainless steel. There are also slight differences between its different models. These applications of glass reactor are divided into explosion-proof and non-explosion-proof. If you choose explosion-proof, the price will also increase a little. However, many industries now require explosion-proof. If it should not be explosion-proof, the problem is still very serious.
 
2. Clarify your needs
Glass reactors can be applied to many industries, but the requirements and work of different industries are also different, so there will be some differences in the required equipment. Demanders can analyze their work needs in advance, and then make purchases based on the advantages and disadvantages of the product. That is more in line with the requirements.
