Opaque Quartz Tube

Opaque quartz tube

1. made of quartz,high in opacity,good quality,its surface is smooth
2. it is widely used in heater,microwave oven,electrical baking oven,sterilization container and so on
3. physical properties:

opalescence SiO2 Thermo-stability
Spectral transmission at less than 500nm SiO2＞99.5% Keep under 900℃ for 15 minutes,then put into 20℃ water 3 times,no crack

4.dimensional tolerance
