1200C Split Tube Furnace with Optional Quartz Tube 60, 70, 80, or 100 mm O.D. & Flange - OTF-1200X series

0.0/5 rating (0 votes)

Description

OTF-1200X-UL furnace is configurated to meet UL/CSA certificate standard. The furnace can adopt a 60, 70, 80 or 100mm O.D quartz tube and a pair of stainless steel vacuum sealing flanges with needle valves & gauge allow heating samples under vacuum or gas flow conditions. The temperature of this tube furnace is controlled by a high precision digital controller which provides 30 programmable segments with +/- 1°C accuracy. The max. working temperature is 1200°C. 

 

SPECIFICATIONS:

Furnace Structure
  • Double-layer steel casing with air cooling keeps furnace surface temperature lower than 60°C.  
  • High purity fibrous alumina insulation for maximum energy saving.
  • The special refractory coating on liner and heating element to increase furnace life.
  • Split cover with Interlock protectioncut the power if the door open during furnace heating process.

Refractory Blocks
  • Two fibrous ceramic tube blocks are included for blocking heat radiation from the inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
  • Quartz blocks (optional) are ideal for a cleaner processing and higher vacuum efficiency.
  • You may order flange support to avoid tube rotating ( click Pic below right )
    
Vacuum Flange

       
  • One pair of SS 304 vacuum flange is included
  • Left flange:
    • one thermal feedthrough (for 1/4O.D sheathed thermocouple)
    • one needle valve
    • one mechanical vacuum gauge -0.1Mpa to 0.15Mpa
    • one barb fitting ( click PiC, below left-2 for detail)
  • Right flange:
    • one KF-25 vacuum port and one needle valve.
  • Optional
  • An anti-Corrosive gas-type independent (above 10mbar) digital vacuum gauge with a wide range between 3.8x10-5 to 1125 Torr is optional. Aside from greater measurement precision, this gauge reduces the risks of chamber explosions caused by the incorrect reading of gas pressures due to gas-type dependency.
  • The flange with quartz window is available for in-situ Raman or Mossbauer analysis
  
Vacuum Pressure
  • 10E-2 torr by a quality mechanical vacuum pump 
  • 10E-5 torr by the turbopump.
  • The vacuum pump is optional. Please click here to choose a vacuum pump.
