Brand:NANBEI Model:NB-5L The double-layer jacketed glass reactor is designed with double-layer glass. The inner layer can be filled with reaction solvent for stirring reaction, and the interlayer can be passed through different cold and heat sources (refrigerated liquid, hot water or hot oil) for cyclic heating or cooling reaction. Under the set constant temperature condition, in a closed glass reactor, the stirring reaction can be carried out under normal pressure or negative pressure according to the requirements of use, and it can be used for the reflux and distillation of the reaction solution. It is a modern fine chemical factory, biological pharmacy and Ideal pilot and production equipment for synthesis of new materials.
