Double Glass Reactor

The Double Glass Reactor, also known as a double-jacketed glass reactor, is a versatile and sophisticated laboratory apparatus widely utilized in chemistry, pharmaceutical research, and material science for conducting reactions under controlled temperature and pressure conditions. It features a dual-layer construction, with an inner glass vessel encased within an outer glass jacket, separated by a space designed for circulating a temperature-regulating fluid, such as water or oil.

This innovative design enables precise temperature control, allowing researchers to maintain reaction temperatures ranging from cryogenic to high temperatures without directly exposing the reaction mixture to external heat sources. The double glass construction further ensures chemical resistance, making it suitable for handling a wide variety of solvents and reagents.

Equipped with a stirrer system, typically magnetic or propeller-driven, it facilitates efficient mixing of reaction components, enhancing reaction kinetics and yield. Additional features like reflux condensers, pressure gauges, and temperature controllers can be integrated to meet specific experimental requirements.

The reactor's transparent walls facilitate visual monitoring of the reaction process, enabling researchers to observe color changes, precipitate formation, or gas evolution in real-time. Moreover, its modular design allows for easy cleaning and maintenance, making it an indispensable tool for researchers conducting sensitive or complex reactions.

The Different Sizes We offered

 

As an important laboratory and industrial production equipment, double-layer glass reaction vessels can be classified into various types according to actual application needs and specification standards. Specifically, they are usually distinguished by their capacity, mainly including small reaction vessels with a capacity of generally less than 10 liters, suitable for small-scale chemical reactions or experiments; Medium sized reaction vessels with a capacity range of 10 to 50 liters, capable of meeting the needs of medium-sized synthesis or preparation; And large reaction vessels, with a capacity exceeding 50 liters, are commonly used in large-scale industrial production or research projects.

In addition, double-layer glass reaction vessels can also be classified based on design characteristics and functional differences. The ordinary reaction kettle is a relatively basic style, suitable for conventional stirring, heating, and cooling operations; High pressure reactors are specially designed to withstand high internal pressures and are suitable for chemical reactions that require high-pressure conditions; The multifunctional reaction kettle integrates more advanced functions, such as precise temperature control, vacuum operation, and multiple stirring methods, to meet complex and varied experimental and production needs.

In food processing, the double glass reactor can potentially be utilized in situations where gentle heating, mixing, or reacting of food ingredients is required under controlled conditions. The double-wall design allows for effective temperature control, ensuring uniform heating throughout the process and minimizing the risk of overheating or hot spots that could compromise the quality or safety of the food product.

It's important to note that when considering the use of a double glass reactor in food processing, strict adherence to food safety regulations and hygiene standards is crucial. The reactor must be made of materials that are safe for food contact, and thorough cleaning and sanitization procedures must be in place to prevent cross-contamination and ensure the integrity of the final product.

In the context of food processing, adhering to strict food safety regulations and hygiene standards is paramount to protecting public health and maintaining consumer trust.

It's essential that the materials used in its construction are certified as safe for food contact. Typically, the inner glass layer of such reactors is made of borosilicate glass, which is known for its chemical resistance, thermal stability, and low reactivity with food products. However, it's also important to consider the materials used in any gaskets, seals, or other components that may come into contact with the food or processing fluids.

In addition to material safety, thorough cleaning and sanitization procedures are critical to prevent cross-contamination and ensure the integrity of the final product. This includes regularly scheduled cleaning and maintenance of the reactor and all associated equipment, as well as the use of approved cleaning agents and sanitizers that are safe for both the reactor materials and the food products being processed.

It's also important to note that the design and operation must be carefully considered to minimize the risk of contamination. For example, the reactor should be designed with smooth, easily cleanable surfaces, and any openings or connections should be designed to minimize the risk of leakage or contamination. Additionally, operators should be trained on proper hygiene practices and should wear appropriate protective clothing and equipment when working with the reactor.

► Applicable catalyst type
1) Conventional catalysts:
The double-jacketed reactor provides a stable temperature and pressure environment, which is essential for the activation of conventional catalysts. Both solid and liquid catalysts can be activated as long as stable temperature and pressure control can be achieved in the double-jacketed reactor.
2) Temperature sensitive catalyst:
For some temperature sensitive catalysts, the precise temperature control capability of the double-jacketed reactor is particularly important. By adjusting the heating or cooling medium in the sandwich, the temperature in the reactor can be precisely controlled, thus ensuring that the catalyst is activated at the optimal temperature.
3) High pressure catalyst:
The double-jacketed reactor also performs well when the catalyst is activated under high pressure. Its robust construction and sealing properties can withstand high pressure environments and ensure the smooth activation of the catalyst.
► The advantages of the catalyst activation process
1) Precise temperature control:
The double jacket design allows a heating or cooling medium to be inserted into the sandwich, enabling precise control of the reaction temperature. This precise temperature control helps to optimize the activation conditions of the catalyst and improve the activation efficiency.
2) Visualization of reaction process:
The wall of the reactor made of transparent materials (such as high borosilicate glass) makes the reaction process clearly visible. This helps experimenters to monitor and adjust the catalyst activation process in real time to ensure the accuracy of the activation effect.
3) High security:
The double-jacketed reactor has an airtight structure, which can effectively prevent the dangerous events such as leakage or explosion that may occur in the reaction process. This ensures the safety of the catalyst activation process.
► Specific application examples
1) Hydrogenation catalyst activation:
The activation of catalyst is one of the key steps in hydrogenation reaction. The double-jacketed reactor can provide a suitable temperature and pressure environment to ensure the effective activation of the hydrogenation catalyst.
2) Oxidation catalyst activation:
Catalysts commonly used in oxidation reactions can also be activated in double-jacketed reactors. By precisely controlling the reaction conditions, the activity and selectivity of the catalyst can be improved.
3) Other types of catalyst activation:
In addition to hydrogenation and oxidation catalysts, double-jacketed reactors are also suitable for activation processes of many other types of catalysts. As long as the activation conditions of the catalyst can be satisfied in the double-jacketed reactor, it can be tried and applied.
