This STF1200 50 x 600mm (OD x length) series, high-quality, split tube furnace has all the features you need to bring your application up to the next level. It’s imbued with spiral wire coils embedded in durable Mitsubishi alumina fiber insulation. A 30-segment digital controller provides precise temperature control. Multiple atmosphere processes can be performed in a single cycle, while heat loss is minimized due to a double-walled steel internal housing.

This furnace is lightweight, portable, and has a small footprint, while its type K thermocouple ensures a long life. It comes with stainless steel vacuum sealing flanges with valves and a pressure meter. Safety features include overheat protection and power failure protection. This and all of our furnaces are CE compliant.


  • Compact, portable and lightweight design.
  • Split 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.

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