The glass reactor manufacturer Zhengzhou Great Wall specializes in the production of double-layer glass, which is mainly used for experiments such as material synthesis, distillation, and concentration. The structure of the kettle body is divided into three types: single layer, double layer and three layers. If necessary, the kettle can be pumped to a negative pressure state to meet the experimental conditions. By adjusting the constant pressure funnel or the regulating valve on the feeding bottle, the material is evenly added. The heat exchange function of the condenser is used to recover the reaction product by distillation. The body of the double-layer speed-regulating glass reaction kettle has two layers, the inner and the outer layers. By injecting a circulating liquid of a certain temperature into the interlayer, the temperature of the material in the kettle is adjusted.
