glass reactorDesigned for double-layer glass, the inner layer can be stirred with reaction solvent, and the interlayer can be heated and cooled by different cold and heat sources (frozen liquid or hot water, hot oil) for circulation. Under constant temperature conditions, the reaction can be stirred under normal pressure or negative pressure according to usage requirements in a closed glass reaction vessel, and reflux and distillation of the reaction solution can be carried out. It is an ideal pilot and production equipment for modern fine chemicals, biopharmaceuticals, and new material synthesis
