is a commonly used biochemical instrument. It is widely used in modern fine chemical, bio-pharmaceutical, scientific research and other industries. It can be concentrated, distilled, recycled, separated and purified under constant speed, constant force and constant temperature. The reaction and other processes are ideal instruments for teaching, experiment, pilot test and production. Glass reactors can generally be divided into two major categories, the first being a double-layer glass reactor and the other being a single-layer glass reactor. Among them, the double-layer glass reactor is a commonly used equipment in the laboratory, and is widely used in the fields of medicine, bio-pharmaceutical and the like.
Simply put, the double-layer glass reactor is based on a versatile single reactor. And after many years of improvement, the reactor is based on a single multi-functional glass reactor, which realizes convenient high and low temperature control, rapid temperature rise, experimental process cooling requirements, modern laboratory, chemical, pharmaceutical and other requirements.
According to the industry, the double-layer glass reactor is made of double-layer glass, and the innermost layer can be placed with reaction solvent for stirring reaction. In addition to this, the sandwich section can be condensed or heated controlled by different temperature requirements.
The double-layer glass reactor has standard components including agitating motor, governor, condenser, continuous titration funnel, vacuum plug, vacuum nozzle, thermometer housing, reaction kettle and two-meter thermal silicone rubber tube. Under constant temperature conditions, the stirring reaction can be operated under normal pressure and under negative pressure according to the use requirements. Further, reflux and distillation of the reaction solution can also be carried out. Therefore, the double-layer glass reactor can be used in the synthesis of biopharmaceuticals, fine chemical plants and new materials.
The kettle body of the double-layer glass reactor is divided into two layers, and the middle portion of the outer layer and the inner layer is called a sandwich layer. The inner layer is used to place the reaction solvent for the stirring reaction. What is the role of the interlayer? According to reports, the glass reactor can not only complete the high temperature experiment but also complete the low temperature reaction. However, the single-layer glass reactor itself has a heating device, and the double-layer glass reactor does not have a sandwich, which plays a very important role.
The industry said that the heating of the double-layer glass reactor is completely completed by the interlayer. Specifically, the double-layer kettle is connected to the circulating oil bath pot interlayer to pass the heat-conducting oil, and the power source can be inserted to heat the material; The same is true for the low temperature reaction, and it is only necessary to replace the solvent in the interlayer with ethanol. The interlayer can make the material heat evenly, and it is convenient to directly observe the stirring reaction process of the material. Therefore, the role of the double-layer glass reactor sandwich is not to be underestimated, which is why the double-layered kettle is becoming more and more popular.
A glass reactor manufacturer said that many customers would ask whether the Jacketed Glass Reactor
is the same as the double-layer glass reactor. Regarding this problem, the industry said that, in fact, if it is structurally simple, both the jacketed glass reactor and the double-layer glass reactor are composed of a kettle body, a kettle lid, a jacket, a transmission device, a shaft sealing device, a stirrer and a support. It is composed of other components, and the stirring method also has paddle type, anchor type, turbine type and the like. And both are produced by GG17 borosilicate glass, which has good chemical and physical properties, and the rotational speed is relatively constant, which can work safely and stably.
However, the double-layer glass reactor is provided with a reaction solvent in the inner layer for stirring reaction, and the interlayer can be heated or cooled by a cold heat source; and the glass interlayer interface of the jacketed glass reactor can be heated by circulating hot oil. It is possible to freeze the cold reaction. Therefore, there is still a certain difference between the two.
