Double-layer glass reactor is a commonly used biochemical instrument. It is widely used in modern fine chemical, bio-pharmaceutical, scientific research and other industries. It can be concentrated, distilled, refluxed, separated and purified under constant speed, constant force and constant temperature. The reaction is the ideal instrument for teaching, experiment, pilot test and production.

The thermostated (high temperature or low temperature) hot solution or coolant is injected through a double-layer reactor sandwich, and the contents of the reactor are heated or cooled at a constant temperature, and uniform stirring can be provided. The material is reacted in the reaction kettle, and the evaporation and reflux reaction of the reaction solution can be controlled, and the kettle lid and the stirring system can be raised as a whole, and the kettle body is rotated by 150 degrees, and the relatively thick material can be directly poured out to facilitate the cleaning kettle. The liquid material can also be discharged from the discharge port of the bottom of the kettle, which is extremely convenient to operate. It is an ideal equipment for modern chemical samples, petrochemicals, sample experiments, biopharmaceuticals and new materials.


1. The reactor body is made of borosilicate glass (GG-17), which has excellent physical and chemical properties, and the bottle is transparent and visible.

2. The main body is made of stainless steel frame + aluminum alloy, which is beautiful and strong and corrosion resistant.

3. Stainless steel stir bar is surrounded by PTFE, suitable for a variety of solvent agitation, pollution-free and corrosion-resistant.

4. The stirring motor and the lifting motor are all low-speed booster motors, which are stable in operation, large in torque, non-sparking and long in life.

5. PTFE components + mechanical seals, proprietary technology, good vacuum and long service life.

6. This product governor is the speed and temperature double digital display. The speed can be set by the speed control knob, which is intuitive and convenient. It is also equipped with a temperature probe (PT100) in the kettle (the temperature of the material in the kettle can be displayed).

7. The overall structure is compact and reasonable, with a brake universal wheel, which can be moved as a whole and is easy to operate.

8. There is no dead angle glass oblique discharge valve, which can effectively reduce the dead angle of mixing and convenient feeding.

9. This product is equipped with a vacuum display function, which can select the best working vacuum for high boiling point materials.
