Clear Fused Quartz Tube(code:1001)
This is clear fused Quarta tube available as continuous machine drawn and automatic
Controlled tubing.This glass has the typical characteriastics of high purity,good
spectral transmission,well controlled dimension and lower OH and so on .This glass can be supplied
in the range of 2-160mm outside diameter,0.6-5.0mm wall thickness and 500-3000mm length.
Exhaust tubes with good CPK are suitable for high-speed streamline production.OH-content can be controlled within 20ppm/15ppm/10ppm/5ppm/2ppm according to the requirement of customers.
The detailed dimensional tolerance and technical data can be found in table I,table I I,table III and table IV.
