Why does a glass reactor require a circulating chiller and heater?

The common glass reaction vessels on the market can be divided into three categories: negative pressure glass reaction vessels, vacuum glass reaction vessels, and high-temperature and high-pressure stirred glass reaction vessels.

The glass reaction kettle mainly utilizes its double-layer glass characteristics. We can place reaction materials in the middle interlayer and stir the reaction under normal pressure or negative pressure. The glass reaction kettle injects a constant temperature hot solution or cooling liquid through the double-layer reaction kettle interlayer to heat or cool the materials inside the reactor at a constant temperature, and can provide stirring. In this way, the medium inside the interlayer of the glass reactor is stirred to perform a cyclic reaction, achieving heating or cooling effects. It is a commonly used biochemical instrument widely used in modern fine chemical, biopharmaceutical, scientific research and experimental industries. It can perform concentration, distillation, reflux, separation, and purification reactions under constant speed, force, and temperature conditions. It is an ideal instrument and equipment for teaching, experimentation, pilot testing, and production.

The double-layer glass reactor can provide high-temperature reaction (the maximum temperature can reach 300 ℃); The double-layer glass reactor can also perform low-temperature reactions (the minimum temperature can reach -80 ℃); A double-layer glass reactor can be evacuated to perform vacuum depressurization reactions. Its unique design makes the temperature control of the experiment more precise, ensuring that the experiment is conducted in a safer environment.

During experiments and production processes involving high or low temperature reactions, glass reaction vessels typically require a circulating chiller and heater to achieve precise temperature control.

The following situations explain why these two devices are needed:

Wide Temperature Range: When the reactor needs to operate over a wide temperature range, requiring both high-temperature reactions (such as up to 250 ℃ or above) and low-temperature reactions (as low as -80 ℃ or lower), it must be equipped with both a heater and a circulating chiller. A heater is used to heat the reaction medium, while a chiller is used for cooling to achieve the required reaction conditions.

High Temperature Control Accuracy: In experiments that require high temperature control accuracy, such as drug synthesis, fine chemical production, etc., the combination of circulating chillers and heaters can provide more accurate temperature regulation. Through closed-loop control systems, such as PID control, the temperature inside the reactor is maintained to have minimal fluctuations near the set value.

Continuous production or complex reaction processes: In complex reaction processes that require continuous production or involve multiple temperature stages, rapid response and precise adjustment of heating and cooling equipment have become particularly important. The integrated use of chillers and heaters can quickly adjust the temperature of the reaction vessel to meet the process requirements of different stages.

Thermal Management: A large amount of heat may be generated during the reaction process, and the chiller needs to remove excess heat in a timely manner to prevent overheating. At the same time, the heater can provide necessary heat supplementation in the early stage or low-temperature reaction stage.

Improving efficiency and product quality: Accurate temperature control can optimize reaction rate, improve product yield and purity. The combination of chiller and heater can significantly improve experimental or production efficiency and product quality.
