Double layer glass reactor - Jacketed glass reactor
1. Use and scope of use:
Introduction: Our company designs and manufactures a 1-100L double-layer glass reactor and its associated heating/cooling cycle unit. The double-layer glass reactor can be stirred at a high temperature by a high-temperature heat source (oil bath) (the maximum temperature can reach 300 ° C), or can be stirred by a low-temperature refrigerant (coolant) (the lowest temperature can reach -80 ° C); The layer glass reactor can be subjected to a normal pressure reaction under normal pressure conditions, or a vacuum negative pressure reaction can be performed by a vacuum device. Moreover, its unique design can withstand a certain positive pressure, which makes the test safer and more convenient. It is an ideal small test, pilot test, and production equipment for the synthesis, separation, extraction and concentration of modern fine chemicals, bio-pharmaceuticals, and new materials.
Working principle of double wall glass reactor and jacketed glass reactor: The reaction medium is placed in the inner layer of the double-layer glass reactor, and the constant temperature is injected into the double-layer glass reactor jacket (high-temperature hot water, heat transfer oil or low-temperature freezing) Liquid) The material in the reactor is heated or cooled at a constant temperature, and mechanical agitation can be provided. The sealed glass reactor was subjected to a vacuum stirring reaction under a set constant temperature condition, and the reaction was concentrated by distillation, and the extraction reaction was separated to synthesize a crystallization reaction, a reaction heat generation, and the like. After the experiment is completed, the material can be discharged from the Teflon discharge port at the bottom of the kettle, which is extremely convenient to operate.
2. Main structure:
The glass reactor vessel is made of GG17 borosilicate glass and 304 stainless steel material, including kettle lid, kettle body (double glass reactor), condenser, distillation flask, constant pressure dropping funnel, agitator, 304 stainless steel well Frame, low temperature circulating oil bath and other components. It has the characteristics of transparency, corrosion resistance and high temperature resistance, which is convenient for the operator to observe the reaction changes of the medium in the kettle, which is very intuitive, safe and reliable. The mixing method is mechanical agitation mechanical seal, strong stirring force and no leakage.
