Brand:NANBEI Model:NBF-50L The reaction solvent can be placed in the inner layer of the single-layer glass reactor for stirring reaction, and the interlayer can be circulated through the cold and heat source (refrigerant, water, heat transfer oil), so that the inner layer can be heated or cooled at a constant temperature, and the distillation and reflux of the reaction solvent can be controlled. , The double-layer glass reactor is an ideal test and production equipment for modern synthetic chemical, biopharmaceutical and new material preparation.
