Quartz glass tubes are widely used in industries requiring high-temperature resistance, chemical stability, and optical transparency. Our quartz glass tubes can withstand 1200°C for long-term use, with a softening point of 1700°C and short-term temperature resistance up to 1450°C. This makes them ideal for semiconductor manufacturing, laboratory research, industrial heating, and UV sterilization.
1. What is a Quartz Glass Tube?
A quartz glass tube is a hollow cylindrical structure made from high-purity quartz. Unlike ordinary glass, quartz glass has superior thermal, chemical, and optical properties, making it highly durable in extreme environments.
