Product Details

The feature of the clear quartz glass tubes is as follows: high purity, strong transmission, strict size control, low OH content and so on. The deep processing would be done according to client's requirements, like neat cutting, fire polish, bending, sealing, polished and so on. OH content can be controlled less than 20ppm\15ppm\10ppm\5ppm\2ppm.

Divide into these series : clear quartz glass tube (OD :1.5mm to 300mm), filter UV quartz tube, colorful quartz glass tube, Milky white tube and so on.

Property:

1. Incredibly thermally shock resistant (can be taken from red heat and plunged into water without cracking)4. Good chemical resistance
2. Low thermal coefficient of expansion (TCE) and high softening temperature5. Excellent electrical insulator
3. Optical transmission properties from ultra violet to infra red6. High radiation resistance
