1800C tube furnace uses 1800C MoSi2 heating elements as its heating element. Hearth is built with Ai2O3 fiber materials. Temperature of this furnace is controlled by high precise SCR power controller with +/-1 °C accuracy and 51 programmable segments up to 1800°C This furnace is built with double layer steel casing and air cooling, two cooling fans inside the case keep the temperature lower. The tube is sealed by stainless steel vacuum sealed 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.
