Description

Technical Field

[0001] The utility model relates to the technical field of glass reactors, in particular to a glass reactor for small-scale trial use of liquid medicine. Background Art

[0002] The inner layer of the glass reactor is used to place the reaction solvent for stirring reaction. The interlayer circulates the cold and heat sources to make the inner layer achieve constant temperature heating or cooling reaction, and can control the distillation and reflux of the reaction solvent. The double-layer glass reactor is an ideal test and production equipment for modern synthetic chemical industry, biopharmaceuticals and new materials preparation. Secondly, the glass is transparent, which means that the changes of the reactants can be observed in real time during the reaction process. When conducting small-scale tests on the drug solution, a glass reactor is needed to observe the changes of the reactants in the reactor.

[0003] Although the existing glass reactor is convenient for observing the changes of the reactants in the reactor when in use, the reactor is made of glass, which makes it fragile and easily damaged by collision. The existing glass reactor has poor protection performance for the reactor body and is inconvenient to use. Therefore, we propose a glass reactor for small-scale trial use of liquid medicine to solve the above problems. Utility Model Content
