OTF-1200X-UL furnace is configurated to meet UL/CSA certificate standards. The furnace can adopt a 60, 75, 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 A 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 the liner and heating element increases furnace life. Split cover with Interlock protection, cut the power if the door opens during furnace heating process. Voltage and Power Input voltage 208 - 240VAC Single Phase, 50/60Hz3KW, Circuit breaker 20A Heating Temperature Fe-Cr-Al Alloy doped by Mo Max. heating temperature: 1200°C ( inert gas must be filled inside the tube to resist deformation) Vacuum heating temperature: 1000°C under vacuum Heating rate: 20°C /min Ma Themocouple: K type 6" length, 3mm OD with Ceramic Sheath, please click the link to order a spare. Heating Zone Total heating zone length: 440mm (~ 18") Constant temperature zone: 150mm (+/2°C) Temperature uniformity: +/- 10°C @ 1000°C in the center 320mm area +/- 5°C @ 1000°C in the center 220mm area Temperature Controller Proportional–integral–derivative control (PID control) and auto-tune function 30 segments programmed with ramping, cooling, and dwelling steps Built-in over-temperature alarm and thermocouple failure alarm +/- 1 ºC temperature control accuracy Default DB9 PC communication port The software for PC software is included Temperature controller (optional) The temperature controller can be graded to the Eurotherm 3000 Temperature Controller with +/- 0.1°C accuracies. This package includes a Eurotherm 3004 programmer, a communication cable (RS485 - USB), and a software CD.

(Ceramic blocks must be fully inserted into the furnace chamber before heating) Quartz blocks (optional) are ideal for 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.
