Two temperature zones lab vacuum tube furnace with high quality for sale


!OEM and ODM service available!


A. Features of tube furnace

a). Tube muffle furnace, heating element used SiC heater of Vertical installation. When Muffle furnace heating, can ensure uniform temperature in the furnace and Strong and durable.


b). Tube furnace chamber of the use of advanced lightweight aluminum oxide material molding, traditional muffle furnace compared the weight, reduce 40% . Heat preservation effect is good,temperature increase speed increased a times, save energy. Furnace service life by four times.


c). Use double deck ventilation cooling structure, muffle furnace work in high temperature, and the furnace shell surface keep low temperature, avoid scald the operating personnel, safety is greatly increased.

d). The 30 period of programmable intelligent digital temperature controller control temperature, high degree of automation, convenient operation.


e). Canbe installed computer communication module and RS485 communication interface, to realize the remote control.


B. Application of tube furnace

Su tong tube furnace mainly used in chemical analysis, physical decomposition and synthesis,superhard materials (such as ceramic), Rare and precious metal smelting and purification,metal heat treatment of sintering process research and other scientific experiments. Universities and colleges, scientific research institutes, medical and health, petroleum chemical industry, mining enterprise, quality and technology supervision agencies, and other units laboratory, laboratory are the use of such equipment.
