S212-2L double-layer glass reactor’s reaction flask volume is 2L, interlayer volume is 0.8L, stirring diameter of axle is 8mm, and the power of stirring is 40W.

S212-2L double-layer glass reactor is a wonderful product that has combined advantages of domestic and foreign like products. It adopts double-layer glass design, put reaction solvent in internal layer to do stirring reaction, connect different cold and heat sources(refrigerating fluid, hot water or hot oil) to interlayer to do cyclic heating or cooling reaction. Under set constant temperature condition, you can conduct stirring reaction under normal or negative pressure in airtight glass reactor, as well as conducting backflow and distillation of reaction solution.
