ZZKD is specialized in distillation and extraction equipment, Glass reactor is one of our main products and include:2L jacketed glass reactor, 5L jacketed glass reactor, 10L jacketed glass reactor, 50L jacketed glass reactor, 100L jacketed glass reactor,etc.

The main purpose of the vacuum glass reactor is to do constant temperature heating or cooling reaction, so it has extremely high requirements on the glass material.The body of vacuum glass reactor on the market is usually made of borosilicate glass. Why is borosilicate glass so popular?

First of all, let's understand what is borosilicate glass.High borosilicate glass, also known as hard glass, is a kind of high-quality glass that uses the characteristics of glass to conduct electricity at high temperatures, heats the glass inside to melt the glass, and then processes it through advanced production processes.Because its linear thermal expansion coefficient is (3.3±0.1)×10-6/K, it is also called "borosilicate glass 3.3".The high borosilicate glass used in the vacuum glass reactor is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. It is widely used because of its excellent performance. Chemical reaction and industry, solar energy, chemical industry, pharmaceutical packaging, electric light source, craft jewelry and other industries.
After understanding what is high borosilicate glass, I believe you will understand why the vacuum glass reactor should use high borosilicate glass.On the one hand, when ordinary glass is subjected to a cooling reaction, it is easy to explode after being heated and put into cold water, and the biggest advantage of high borosilicate glass is high temperature resistance.Compared with ordinary glass, the high borosilicate glass used in the vacuum glass reactor has high heat resistance, will not burst, has higher transparency, smoother glass body, is not easy to be adhered to by dirt, and is easy to clean.
On the other hand, there are many kinds of solutions used in the experiment process of vacuum glass reactor. Borosilicate glass also has the advantages of acid and alkali resistance for special solutions.The fire resistance and physical strength of this glass is an ideal choice for laboratories. It is used to make high-durability laboratory equipment such as beakers and test tubes. This is the reason why high borosilicate glass is more and more popular with vacuum glass reactor manufacturers.

In addition, the high borosilicate glass used in the vacuum glass reactor is also used in some areas of production and life: for example, common glass cookware in the kitchen, high-quality beverage glassware, space shuttle insulation tile coating, and so on.
