Clear Fused Quartz Tubes

Our Clear Fused Quartz Tubes are perfect for your laboratory and manufacturing needs. Produced from pure quartz, they provide exceptionally high purity, excellent thermal shock resistance, good temperature uniformity, and are perfect for high temperature applications up to 1650°C.

Important Notice:
Because 1219mm quartz glass pipe is fragile item, after pakage is over size. So if you need full length tubes, please contact us.
