The glass reactor is divided into a double-layer glass reactor and a single-layer glass reactor. The double-layer glass reactor interlayer can provide high-temperature reaction (the high temperature can reach 300 °C); the double-layer glass reactor can also be used for low-temperature reaction ( The low temperature of zui can reach -80 ° C); the double-layer glass reactor can be vacuumed and subjected to a negative pressure reaction. And its unique design makes the test safer and more convenient.
Double-layer glass reactor - working principle of double-layer glass reactor
The double-layer glass reactor interlayer is injected with a constant temperature (high temperature or low temperature) hot-dissolving medium or a cooling medium, and the contents of the reactor are heated or cooled at a constant temperature, and stirring can be provided. The material is reacted in the reaction vessel, and the evaporation and reflux of the reaction solution can be controlled. After the reaction is completed, the material can be discharged from the discharge port at the bottom of the kettle, and the operation is extremely convenient. It is an ideal equipment for modern chemical samples, sample experiments, biopharmaceuticals and new materials. Can provide high temperature reaction (configure the corresponding circulating oil bath, zui high temperature can reach 300 ° C); can also do low temperature reaction (configure the corresponding low temperature freezing liquid circulation system, zui low temperature can reach -80 ° C); Vacuum is drawn to perform a vacuum reaction. Moreover, its unique design makes the test safer and more convenient.
