Tube furnace with resistance wire as the heating element, double shell structure, an intelligent program temperature control system, silicon control, and high-precision temperature control. The double shell with the air-cooling system effectively reduces the surface temperature of the furnace shell. This tube furnace, combined with our standard vacuum gas mixing system, can be evacuated through the atmosphere. The tube furnace cover can be opened to quickly cool down the structure which gives a reasonable, beautiful appearance.

Tube furnace is mainly used in glass, metallurgy, heat treatment, lithium anode materials, new energy and other industries, it is a professional equipment for measuring materials under specific temperature conditions. Its structure is simple, easy to operate, easy to control, and suitable for continuous production. In addition, tube furnace is also widely used in chemical vapour deposition (CVD) and plasma enhanced CVD systems.
Laboratory tube furnaces are often used as external heaters and are known as "hot-wall heaters", a classic design.Depending on the operating temperature, the tubes are usually made of transparent quartz tubes, high-purity alumina ceramic tubes, and high-strength metal alloy tubes. In order to meet different thermal research requirements, tube furnaces can be designed with multiple heating zones for flexible control of the temperature gradient in the working chamber; the tubes can be operated in controlled atmospheres or in a high vacuum to suit different operating requirements.
The heating elements of the tube furnace are arranged around the cylindrical chamber and the chamber provides indirect thermal radiation heating of the sample inside the cylindrical chamber. Since the design of the furnace tube effectively prevents the sample material from coming into contact with the heating elements and the insulation, the tube furnace provides a clean and isolated thermal chamber, thus reducing the risk of contamination of the sample material by the chamber.
