1200°C Split Tube Furnace with UL Recognized Components - OTF-1200X-UL

0.0/5 rating (0 votes)


OTF-1200X-UL series furnaces are the split-able tube furnaces using UL recognized electric components with working temperature of 1200°C max/. The furnace can adopt a 60mm, 80mm 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.


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.
  • Special refractory coating on liner and heating element to increase furnace life.
  • All electric components are UL or Met recognized and ready to pass any safety test worldwide
Input Voltage 208 - 240VAC SINGLE PHASE, 50/60Hz

Heating Temperature
  • Max. heating temperature: 1200°C (N2 or other inert gas must be filled inside the tube to resist deformation)
  • Continuously heating temperature: 1100°C
  • Heating rate: 20°C /min Max.
Heating Zone
  • Total heating zone length: 440mm (~ 18")
  • Constant temperature zone: 150mm (+/1°C)
