1200C 3-Zone Top-Open Tube Furnace w/ Kanthal Heating Elements


Ai TFM3 series 3-zone tube furnaces feature the famous Kanthal (Sweden) resistance wire as their heating elements. Furnace hearth is built with Mitsubishi (Japan) high quality fiber materials. Temperature of this furnace is controlled by high precision temperature controller (Shimaden fp93 from Japan) with /-1 °C accuracy and 40 programmable segments. Furnace housing is built with double-layer steel and two cooling fans inside keep the furnace body temperature low. 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.
