Brief Introduction

Glass reactors are mainly used for synthetic reaction, distillation and concentration of different types of materials. We have single wall, double wall and triple wall glass reactors. The reactor can be pumped to a negative pressure state according to some experimental requirements. A constant pressure funnel or an adjusting valve on the feeding bottle allows you to add material to the vessel at a uniform and controlled speed. Condenser helps to recover some materials distillated during reaction. Circulating liquid can be filled into the jacket to heat or cool materials inside. Triple wall glass reactor with two jackets, the inner jacket is for circulating liquid, and the outer layer should be pumped to vacuum condition for thermal insulation.


Glass reactors are widely applied in the experiment, middle-scale test, and production of chemistry, fine chemical engineering, biological pharmacy and synthesis of new materials. Glass reactors can be made into system devices with multi-purpose circulating water vacuum pump, diaphragm vacuum pump, low temperature circulating pump(vacuum), circulating cooler, constant temperature circulator, low temperature cooling liquid circulating pump, high temperature heating bath circulator and hermetic cooling and heating circulator.
