Double-layer glass fractional reactor is designed with double-level glass. The reaction material is put into the inner, which can be stirred. With the different cold and hot mediums (refrigerating fluid, hot water, and hot oil), do some heat circulations and cooling reactions. Under the constant temperature and ordinary pressure, as well as negative pressure, the stirring reaction can be done in seal glass reactor, also back-flow, distillation, etc..
