Product Overview
Small Tube Furnace adopts a quartz tube and a pair of stainless steel vacuum sealing flanges with needle valves & gauge, which allows heating samples under vacuum or gas flow conditions. The temperature of this tube furnace is controlled by a high-precision digital controller which provides 32 programmable segments with +/- 1°C accuracy. The max. working temperature is 1200°C.

Main Features

  • Tmax 1200°C
  • Dual steel structure, state-of-the-art design (Stainless Design Available)
  • Multiple atmosphere processes in a single cycle are available
  • Max Vacuum level achieve 10E-5 torr worked with molecular pump
  • Fiber-insulated chamber with all sides embeded heating wires ensure uniform temperature
  • Shimaden PID temperature controller with programmable 32 segments
  • SS304 vacuum sealing flanges with valves and pressure meter included
  • Split furnace chamber for fast and easy tube access
  • Long life type N thermocouple
  • CE certified, standard

Safty Measures

  • Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
  • Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller’s manual) or when the thermocouple is broken or malfunctions
  • Power failure protection resumes furnace operation right after the point of failure when power is reestablished
  • Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot

Application Notes

  • Don’t fill any explosive gasses such as Hydrogen or Methane into the tube without necessary safety controls and supervision.
  • Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa.
  • Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating
