This listing is one brand new STF1200 1200°C split tube furnace with two 60mm OD x 1000mm L quartz tubes.

STF1200 series split tube furnaces feature the famous Kanthal spiral wire coils embedded in alumina fiber insulation. A double walled steel internal housing helps minimize heat loss to exterior surface.
Furnace operation is controlled by Shimaden 40-segment digital controller with built-in RS485 digital communications port and USB adaptor, allowing the user to connect to a PC for remote control and monitoring of the furnace. You can also save or export test results.

All 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.)
  • Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
  • Built-in computer interface.
  • Long life type K thermocouple.
  • One year warranty with lifetime US-based parts and service support.


  • 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.
