Researchers of Hamadan Islamic Azad University have designed and made High Vacuum Tube Furnace which can be applied in creating conductive and non-conductive coatings, antibacterial layers and multi-layer coatings for solar cells.

According to an ISCA report, typical applications of tube furnaces include the purification, coating, drying, hardening or ageing of samples. Among other uses, a tube furnace can also be used for annealing, brazing, calcination, degassing, sintering, soldering, sublimation, synthesis, and tempering. In a laboratory a tube furnace could be used for thermocouple calibration, in the testing of fuel cells, or in catalyst research.

The Faculty Member of Hamadan IAU Physics Department, Seyed Ali Asghar Trohid stated that melting metals, alloy making, heat treating and etc. are some other applications of this furnaces. These high vacuum furnaces are often the starting point for additional customization such as automated control of gate valves, gas purge, back-fill systems and coordinated control of roughing pump with the turbo-molecular high vacuum pump.

Another researcher, Azadeh Jafari noted that the Tube Furnaces has been designed inexpensively with high efficiency, and controlling and measuring physical and chemical properties of the product in nano-meter dimensions, were the main purpose of this research.

The tube furnace range GHA (single zone) / GHC (three zone) uses free radiating wire elements embedded within the insulation of the furnace body. The benefit of this design is its flexibility; with the use of tube adapters the same furnace can be used with a variety of tube diameters.
