Upgrade to Eurotherm Temperature Controllers (Dual zone)
GSL-1700X-60-II is a CE certified dual zones tube furnace. Each heating zone is 12" in length and controlled by two precision 30 segments digital temperature controllers independently. One zone is heated by MoSi2 elements up to 1700ºC, and another zone is heated by SiC element up to 1400ºC, So the tube furnace can create the various thermal gradient by adjusting two zone temperature. It is excellent furnace to prepare functional materials under thermal gradient, and also can be used for epitaxial film growth by CVD or PVD with a vacuum system.


Furnace structure

  • Double layer steel case with two cooling fans, which ensure low surface temperature
  • High purity fibrous alumina insulation for energy saving


  • 9 KW
  • Require 60A Air breaker switch


  • AC 220-240 Single Phase, 50/60 Hz

Heating Zone Length

  • Two zones heated separately
    • Zone 1:  working temperature  800 - 1500ºC (Heated by SiC ),  length: 12" (300 mm), Thermocouple: S-type
    • Zone 2:  working temperature  800 - 1700ºC  (Heated by MoSi2) heating 12" (300 mm), Thermocouple: B-type
  • Constant temperature zone length: 14" (300mm) within +/-1ºC if two zone at same temperature < 1500oC
  • Max. Heating rate: 10ºC/min

    How to set up ceramic tube and vacuum flange for MTI Tube furnace


    Click here to learn more about the installation of a gas regulator.
    • The tube furnaces with alumina tube are designed for using under vacuum and low pressure < 0.02 Mpa / 0.2 Bar/ 3 PSI
    • Never use graphite crucible in alumina tube.
    • Vacuum pressures may only be safely used up to 1500°C. The flow rate for gasses should be limited to <200 SCCM (or 200mL/min) for reducing thermal shocks to the tube. 
    • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
    • Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
