Product Description

fused quartz tube and rod       

Clear fused quartz tubing is a high purity (99.99%+) quartz glass suitable for temperatures up to 1600 C.  Resistance to thermal shock is another important property of quartz tubing. Most sizes shown are available in either 4 or 5 feet length furnace cuts.  Trim cuts are available on request at no additional charge.
