twin quartz tubes

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.
These tubes surface glossy milky-white color, high purity, abrasion resistance (any acid except HF acid), high temperature,
steady heat remain, high insulation, long using life, no contamination,
this material is widely used in far infrared heater and drying equipments applications.
Available to absorb the far infrared spectrum with wavelength under 4 U,
it makes the tube body itself heat and increase the heat energy radicalization.
At the meanwhile, the wavelength at 5-13 U area far infrared wave bands transmit rate reach onto 90%.
material needing heat to dry (it is generally at 3-25u areas,
it has strong absorption) Offer most effective alternative absorption to heat material component.
This feature is not available with any other far infrared material
