Product Detail
Cear Fused Quartz Tubes
Made of high purity quartz sand,SiO2 over 99.99%,various outer diamter from 1mm to 400mm,wall thickness 0.2mm to 8mm,widly used for making uvc lamp,quartz heaters,lab test tubes,furnace tubes etc.
This is clear fused quartz glass tube available as continuous machine drawn and automatic controlled tubing.It has the typical characteriastics of high purity ,good spectral transmission,well controlled dimension and lower OH.it serves as the first choice of heat resistant material for halogen lamps, mercury lamps,metal halide lamps and other quartz lamps.This quartz tube can be supplied in the range of 2-350mm outside diameter,0.2-8mm wall thickness and max over 3000mm length.Exhaust tubes with good CPK are suitable for high-speed streamline production .and further processing of trim cutting ,fire polishing ,bending and pinching can be done according to the requirement of customers .OH-content can be controlled within 20ppm\15ppm\5ppm\2ppm according to the requirement of customers
