Originally published as What is a double-jacketed glass reactor? Glass reactor is a commonly used biochemical instrument, which is widely used in modern fine chemicals, biopharmaceuticals, scientific research experiments and other industries. It can do concentration, distillation, reflux, separation, purification reactions and other processes under the conditions of constant speed, constant force and constant temperature. It is an ideal instrument and equipment for teaching, experiment,wiped film evaporator, pilot test and production. Glass reactors can generally be divided into two categories, one is the double glass reactor, and the other is the single glass reactor. Among them, the double-layer glass reactor is a commonly used equipment in the laboratory,thin film distillation, which is widely used in medicine, biopharmaceuticals and other fields. To put it simply, a double-glazed reaction kettle is a single reaction kettle based on multiple functions. And after years of improvement, the reaction kettle is based on a single multifunctional glass reactor, so that the requirements of convenient high and low temperature control, rapid temperature rise, cooling in an experimental process, jacketed glass reactor ,nutsche filter dryer, a modern laboratory, chemistry, pharmacy and the like are met. The double-layer glass reaction kettle is made of double-layer glass, and the inner layer of the reaction kettle can be placed with a reaction solvent for stirring and reaction. In addition, the sandwich portion can be controlled for condensation or heating by different temperature requirements. The double-layer glass reactor has standard components including a stirring motor, a speed regulator, a condenser, a continuous titration funnel, a vacuum plug, a vacuum suction head, a thermometer shell, a reaction kettle and a two-meter heat-conducting silicone rubber tube. Under the condition of constant temperature, the stirring reaction can be carried out under normal pressure and negative pressure according to the use requirements. Reflux and distillation of the reaction solution can also be carried out. Therefore, the double-glass reactor can be used in biopharmaceuticals, fine chemical plants, and the synthesis of new materials. The kettle body of the double-layer glass reaction kettle is divided into two layers, and the middle part of the outer layer and the inner layer is called an interlayer. The inner layer is used to place the reaction solvent to stir the reaction. What is the function of the interlayer? According to the introduction Glass reactor can not only complete high temperature experiments, but also complete low temperature reactions. However, the single-layer glass reactor has its own heating device, while the double-layer glass reactor does not, so the interlayer plays a very important role. According to the industry, the heating of the double-layer glass reaction kettle is completely completed through the interlayer. Specifically, the double-layer kettle is connected to the circulating oil bath with heat conducting oil in the interlayer, and the materials can be heated by plugging in the power supply. The same is true for low-temperature reaction, as long as the solvent in the interlayer is replaced by ethanol. The interlayer can uniformly heat the materials,wiped film distillation, and the stirring reaction process of the materials can be conveniently and directly observed. Therefore, the role of the interlayer of the double-glass reactor is not to be underestimated, which is also the reason why the double-glass reactor is becoming more and more popular.
