Flexible use of multi-functional double glass reactor

Glass reactor is a commonly used biochemical instrument, which is widely used in modern fine chemical industry, biopharmaceutical industry, scientific research experiment and other industries It can do concentration, distillation, reflux, separation, purification reaction and other processes under constant speed, constant force and constant temperature It is an ideal instrument and equipment for teaching, experiment, pilot test and production Glass reactors can be generally divided into two categories, the first is double-layer glass reactor, the other is single-layer glass reactor Among them, the double glass reactor is a kind of equipment commonly used in the laboratory, which is widely used in medicine, biopharmaceutical and other fields The materials in the reactor can be heated or cooled at a constant temperature by injecting a constant temperature (high or low temperature) hot solution medium or a cooling medium into the interlayer of the double glass reactor, and agitation can be provided The materials react in the reactor, and can control the evaporation and reflux of the reaction solution, so that the sealed glass reactor can carry out vacuum stirring reaction, distillation concentration reaction, separation extraction reaction, synthesis crystallization reaction, reaction heating and other experiments under the set constant temperature conditions After the experiment, the material can be discharged from the discharge port of polytetrafluoroethylene at the bottom of the buss, which is very convenient for operation The double glass reactor can do high temperature stirring reaction (high temperature can reach 300 ℃) through high temperature heat source (oil bath), or low temperature stirring reaction (low temperature can reach - 80 ℃) through low temperature refrigerant (coolant); the double glass reactor can do atmospheric pressure reaction under normal pressure, or vacuum negative pressure reaction through vacuum device The unique design of double glass reactor can also bear certain positive pressure, which makes the test safer and more convenient It is an ideal small test, pilot test and production equipment for modern fine chemicals, biopharmaceuticals and new materials synthesis, separation, extraction and concentration In short, the double glass reactor is based on a single multi-functional reactor After many years of improvement, the reactor is based on a single multi-functional glass reactor, which can realize the convenient high and low temperature control requirements The experimental process can be quickly heated and cooled, and meet the requirements of modern laboratory chemistry and pharmacy The double glass reactor is made of double glass, the innermost layer of which can place reaction solvent for stirring reaction In addition, the interlayer part can be controlled by condensation or heating according to different temperature requirements The double glass reactor has standard components, including mixing motor, governor, condenser, continuous titration funnel, vacuum plug, vacuum suction head, thermometer shell, reaction kettle and two meters of conductive silicone rubber pipe Under constant temperature, the stirring reaction can be operated under normal pressure and negative pressure according to the use requirements In addition, reflux and distillation of the reaction solution can also be carried out Therefore, the double glass reactor can be used in the synthesis of biopharmaceuticals, fine chemical plants and new materials The reactor body of double glass reaction kettle is divided into two layers, the middle part of outer layer and inner layer is called interlayer The inner layer is used to place reaction medium for stirring reaction What is the role of interlayer? Glass reactor can not only complete high temperature experiment, but also complete low temperature reaction But the single-layer glass reactor has its own heating device, while the double-layer glass reactor does not, at this time, the interlayer plays a very important role The heating of double-layer glass reaction kettle is completely completed by interlayer Specifically, first, connect the double-layer kettle to the interlayer of circulating oil bath and connect the conduction oil, then plug in the power supply to heat the material; the same is true for low-temperature reaction, just replace the solvent in the interlayer with ethanol The interlayer can make the material heated evenly, and at the same time, it is convenient to directly observe the stirring reaction process of the material Therefore, the role of double-layer glass reactor interlayer should not be underestimated, which is also the reason why double-layer reactor is more and more popular Many customers will ask if the jacketed glass reactor is the same as the double glass reactor? In fact, if viewed from the structure alone, the jacket glass reactor and the double-layer glass reactor are composed of the reactor body, the reactor cover, the jacket, the transmission equipment, the shaft seal equipment, the agitator and the support and other components, and the mixing methods also include the paddle type, the anchor type, the turbine type and so on Both of them are made of GG17 high borosilicate glass, which has good chemical and physical properties, relatively constant rotating speed, and can work safely and stably continuously However, the double-layer glass reactor is a reaction medium placed in the inner layer for stirring reaction, and the interlayer can be heated or cooled at a constant temperature through a cold and heat source; the glass interlayer interface of the jacketed glass reactor can be heated through circulation of hot oil, and can be cooled at a low temperature through freezing Therefore, there are some differences between them Recommendation: Changzhou Jiangnan experimental instrument S212 double glass reactor / electronic constant speed mixer / glass reaction device s212b-2 constant speed mixer / S212B-5 glass reactor / s212b-20 glass double layer reactor
