Glass Reactor vs Glass-Lined Reactor: What’s the Difference and How to Choose?

Reactor is a type of equipment that performs chemical reactions under controlled conditions. Reactors are widely used in various industries, such as pharmaceutical, chemical, biotechnology, and food processing. Depending on the type and nature of the reaction, different materials of construction may be required for the reactor. Two common materials are glass and glass-lined steel.

Glass reactor and glass-lined reactor both contains glass, but they have some differences in their structure, performance, and application. In this article, we will compare glass reactor and glass-lined reactor and explain what they are, how they work, and what are their advantages and disadvantages.

What is Glass Reactor?

Glass reactor is a type of reactor that is made entirely of glass. It consists of a glass vessel with a glass cover and attachments, such as stirrer, condenser, thermometer, valves, etc. Glass reactor allows for full visibility of the reaction process and easy observation of the color change, precipitation, crystallization, and other phenomena.

Glass reactor is suitable for reactions that require high purity, transparency, and corrosion resistance. Glass reactor can also be used for distillation , extraction , reflux , synthesis , and other operations.

Some of the common applications of glass reactor are:

  • Research and development
  • Kilo lab production
  • Pilot plant production
  • Fine chemical synthesis
  • Pharmaceutical synthesis
  • Biotechnology fermentation
  • Food processing

What is Glass-Lined Reactor?

Glass-lined reactor is a type of reactor that is made of steel with a glass coating on the inner surface. The glass coating is fused to the steel at high temperature and forms a strong bond that prevents corrosion and contamination. The steel backbone provide mechanical strength and properties, while the glass coating also provides a smooth and non-stick surface that facilitates cleaning and maintenance.

Glass-lined reactor is suitable for reactions that require high corrosion resistance, high temperature resistance, and high pressure resistance. Glass-lined reactor can handle acidic reactions and can be used for various processes, such as polymerization , hydrolysis , oxidation , reduction , alkylation , etc.

Some of the common applications of glass-lined reactor are:

  • Chemical production
  • Pharmaceutical production
  • Pesticide production
  • Dye production
  • Paint production
  • Cosmetics production

How to Choose Between Glass Reactor and Glass-Lined Reactor?

The choice between glass reactor and glass-lined reactor depends on several factors, such as:

  • The type and level of purity required
  • The type and level of transparency required
  • The type and level of corrosion resistance required
  • The type and level of temperature and pressure resistance required
  • The type and level of mixing required
  • The cost and availability of the material

Generally speaking, glass reactor is preferred for applications at smaller scale that require high purity, transparency, and corrosion resistance than glass-lined reactor. However, at larger scale, especially at commercial production, if high temperature, pressure, or mixing is involved, glass-lined reactor may be a better option to avoid thermal shock , mechanical stress , or abrasion .

For example, in pharmaceutical synthesis , glass reactor is often used for small-scale or laboratory-scale reactions that involve sensitive or transparent substances. On the other hand, glass-lined reactor is often used for large-scale or industrial-scale reactions that involve corrosive or high-pressure substances.

Of course, there are other factors that may influence the choice of material , such as safety , durability , maintenance , and performance . Therefore, it is always advisable to consult with an expert before making a final decision.

Conclusion

Glass reactor and glass-lined reactor are both made of glass, but they have some differences in their structure, performance, and application. Glass reactor is made entirely of glass and allows for full visibility of the reaction process. Glass-lined reactor is made of steel with a glass coating on the inner surface and provides high corrosion resistance , high temperature resistance , and high pressure resistance .

The choice between glass reactor and glass-lined reactor depends on several factors , such as purity , transparency , corrosion resistance , temperature resistance , pressure resistance , mixing , cost , and availability . Generally speaking, glass reactor is preferred for applications that require high purity , transparency , and corrosion resistance than glass-lined reactor .
