Speed-regulation 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.

● Max. working temperature is 200℃, and the max. temperature difference between the internal and external of the reactor is 80℃. When heating or cooling the reactor, it's recomended to monitor the temperature inside and outside the vessel continously and heat up or cool down gradually to avoid accidents.

● Bearable temperature difference: 100℃ (jacketed), 80℃ (double jacketed).

● Reactor vessel can withstand the pressure ranges from -0.1MPa to 0MPa.

● For IIB explosive atmosphere, dIIBT4 standard explosion-proof parts (heater, control box, motor, wires) will be used for safety concern.


Your safety is important to us! Please use caution when operating. Users must take all necessary precautions to avoid contact with rotating parts, particularly entanglement of loose clothing, hair, necklaces, or other jewelry. Under these circumstances, the winding action of the rotating parts can draw the user(s) into the apparatus, resulting in breakage of glassware, burns, and/or chemical exposure. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
