The Double layer stainless steel reactor is designed with double-layer stainless steel. The reaction solvent is placed in the inner layer for stirring reaction, and the interlayer can be connected to different cold and heat sources (refrigeration liquid, hot water or hot oil) for cyclic heating or cooling reaction. Under set constant temperature conditions, in a closed stainless steel reactor, the stirring reaction can be carried out under normal pressure or negative pressure according to the use requirements, and the reaction solution can be refluxed and distilled. It is an ideal choice for modern fine chemical plants, biopharmaceuticals and Ideal pilot and production equipment for the synthesis of new materials.

1. Frequency conversion speed regulation, AC induction motor. The speed is constant, no brushes, no sparks, safe and stable, and can work continuously.

2. The entire set of instruments is made of SUS316L/SUS304 stainless steel, which has good chemical and physical properties.

3. The mezzanine interface is connected with hot oil for circulation and heating reaction can be carried out, and the refrigerant liquid is connected with it for low-temperature reaction.

4. It can react at room temperature, and the reaction heat can be quickly taken away by running tap water on it.

5. The lower discharge port uses a stainless steel ball valve. There is no dead space in the container and it is removable to facilitate the discharge of solid materials.

6. Eight-port reactor cover, extra-large port design for easy cleaning, standard port socket for optional assembly of reflux and distillation synthesis devices.
