Quartz Glass Tube - Highborn International Company

Standard clear quartz glass tube is produced by specialized high purity sand and automatic controlled fusing furnace. It has the characteristics of high purity, strong heat resistance, high transmission and accurate dimension etc. The stable supply of quartz tube with the OH content of 5-20ppm after baking is available. We can also supply the quartz tube with the OH content of 20-50ppm after baking and without baking.

It is widely applied for halogen lamp, mercury lamp, single-ended lamp, automobile lamp, stage lamp, thermocouple, printer lamp, sleeve for water treatment lamp, quartz utensils and pipes etc.
