Originally published as What is a jacketed glass reactor? Double or triple 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, 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,wiped film evaporator, the double-layer glass reactor is a commonly used equipment in the laboratory, 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,wiped film distillation, so that the requirements of convenient high and low temperature control, rapid temperature rise, cooling in the experimental process, a modern laboratory, chemistry, pharmacy and the like are met. The sandwich section 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,thin film distillation, 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, it 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 for stirring reaction. What is the function of the interlayer? According to 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. 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, and the interlayer is filled with heat transfer oil. The power supply is plugged in to heat the materials. The same is true for the low-temperature reaction, as long as the solvent in the interlayer is replaced by ethanol. The interlayer can uniformly heat the materials, 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 can not be underestimated, which is also the reason why the double-glass reactor is becoming more and more popular. Some glass reactor manufacturers said that many customers would ask if the jacketed glass reactor was the same as the double-layer glass reactor? For this problem, the industry said that, in fact, if only from the structural point of view, jacketed glass reaction kettle and double-layer glass reaction kettle are composed of kettle body, kettle cover, jacket, transmission equipment, shaft seal equipment, agitator and support components, stirring methods are also paddle type, anchor type, turbine type and so on. Both of them are made of GG17 high borosilicate glass, which has good chemical and physical properties, relatively constant speed and safe and stable continuous work. However, the reaction solvent is placed in the inner layer of the double-layer glass reaction kettle for stirring reaction,50l rotovap, and the interlayer can be used for constant-temperature heating or cooling reaction through a cold and heat source; while the glass interlayer interface of the jacketed glass reaction kettle can be used for heating reaction through hot oil circulation, and low-temperature reaction can be carried out through refrigeration. Therefore, there are still some differences between the two. Return to Sohu to see more Responsible Editor:. toptiontech.com
