Share the product




The machine has electric constant speed mixing system, condensation and dropping system. It need to be equipped with vacuum device, high-temperature or low-temperature circulation device and other system devices.


  • High borosilicate glass (expansion coefficient 3.3) and polytetrafluoroethylene materials are used for the parts in contact with materials, which has stable performance, is not easy to react with materials, and is convenient and safe to use.
  • The base plate type main body is made of aluminum alloy + stainless steel, which is efficient, stable, beautiful and durable.
  • Glass + Teflon discharge valve, no effusion side discharge, and the recovery of solution is very fast.
  • Electronic stepless speed regulation, which can digitally display the speed through fine-tuning of twist, with stable performance and convenient use.
  • The mixing system adopts double bearing and double skeleton oil seal, which has high temperature resistance, wear resistance and good sealing effect.
  • Vacuum pressure gauge displays real-time vacuum and pointer display.
  • Crescent stirring paddle, 304 stainless steel + polytetrafluoroethylene stirring blade; The mixing rod is made of 304 stainless steel and wrapped with Teflon pipe, with high strength and strong corrosion resistance.
  • Fuse safety protection to ensure the safe operation of the circuit.
