Used Electric Furnace drawing,accord with International standard. Full length of transparent Quartz Tube,Quartz rod,The high purity quartz products, used our own mine, high quality nature crystal as the raw material, go thru advanced technic. At UV wave band 185nm, the wavelength through average about 70%, it is the best material for ozone-free sterilize lamp or sleeve quartz glass tubing. At UV wave band 253.7nm, the wavelength through rate average > 85%, be propitious to Ozone sterilize lamp or sleeve quartz glass tubing.Transparent Quartz tubes widely apply to Semiconductor, Lighting, and Electric heating Industrial field.
