Tube furnace mainly used in chemical analysis, physical decomposition and synthesis,
super hard 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.
1. Gravimetric analysis;
2. Sintering;
3. Quantitative analysis;
4. Heat treating;
5. Glass preparation;
Tube furnace Structure:
High purity alumina fiber insulation surrounding the chamber provides maximum energy efficiency.
Heavy duty double layer structure with cooling fan to keep furnace exteriors safe to touch.
Doble layer sreel case with forced air cooling to ensure lower saferface temperature.
One optional venting port is built on the top of furnace,need at extra cost .
