1400C 2-Zone Tube Furnace With Alumina Tube


TF1400 series tube furnaces feature a chamber with Mitsubishi (Japan) high quality alumina fiber insulation and SiC heating elements. A dual-wall steel internal housing helps minimize heat loss to exterior surface.

Furnace operation is controlled by Shimaden (Japan) 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.

Ai TFM2 series 1400C 2-zone tube furnaces use SiCand MoSi2 as their heating elements. The furnace hearth is built with Mitsubishi (Japan) high-quality fiber materials. Temperature is controlled by Eurotherm (UK) digital multi-segment controller. Furnace housing is built with double-layer steel and two cooling fans inside keep the furnace body temperature low. The furnace tube is sealed by stainless steel vacuum sealing flanges, it can be used under vacuum and other gases condition. This tube furnace is an ideal tool for sintering all types of materials/chemical. Great for labs or college scientific research use.

These furnaces have built-in interface to a computer. We provide connection cable, adaptor and software that can be used to control the temperature and parameters of the furnace, all from your PC! You can also save a temperature curve for record or study purposes.


  • Furnace overheat protection cuts off power when temperature is over the desired range.
  • Thermocouple protection cuts off power when the thermocouple is broken or malfunctioned.
  • Temperature variation protection cuts off power when the difference between actual temperature and target temperature is off the desired range. (refer to controllers manual)
  • Power failure protection resume furnace operation right after the point of failure when power is back up.
  • Stainless steel flange support makes sure the tube and flanges are secure and in their absolute position, it also longer the life of the tube

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