Mini Tube Furnace

Release time:2018-03-01  viewed:931

Equipment description:

Mini tube furnace is an experimental equipment for heat treatment of various materials.The main industries are rare earth preparation, electronic lighting, crystal annealing, biocermals, electronic ceramics, special alloys, magnetic materials, precision casting, etc., mainly used in vacuum sintering, atmosphere protection sintering, vacuum coating, CVD experiment, material composition measurement and other occasions.






Configuration details 

        1. Double air-cooled structure;

        2. High purity Al2O3 fiber refractory insulation material, energy saving and consumption  


        3. High purity alumina coating can prolong the service life of heating element.

        4. The alumina tube plug helps you create a perfect temperature gradient in the tube.
