STF1200 50x600mm (ODxlength) portable top-open tube furnaces feature spiral wire coils embedded in Mitsubishi (Japan) alumina fiber insulation. A double walled steel internal housing helps minimize heat loss to exterior surface. Furnace operation is controlled by a 30-segment digital controller. All our furnaces are CE compliant.


  • Compact, portable and lightweight design.
  • Top-open furnace chamber for fast and easy tube access.
  • Standard package includes set of stainless steel vacuum sealing flanges with valves and pressure meter.
  • Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot.
  • Multiple atmosphere processes in a single cycle are possible (ex: binder burn out in air and parts sintering under rough vacuum or inert gas environment.)
  • Long life type K thermocouple.


  • 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.


NEVER fill furnace with explosive gases, including Hydrogen, Carbon Monoxide and Methane.
