Quartz Glass Vessel/Quartz Glass Test Tube
1.High purity made of 99.99%-99.9999% pure quartz.
2.Strong Hardness, Can reach Morse level 7.
3.High temperature resistance, can work under 1200°C continuously,
and in short time can even work under 1500°C.
4. Acid and Alkali resistance
Except hydrofluoric acid, quartz glass does not react with any acid and base except
hydrofluoric acid. The stability is 30 times of the ceramic, and 150 times of stainless steel
5. Electric insulation, it is 10000 times of usual glass.
6. High light transmittance , it is different from 85%-95% depend on different spectrum.
7.Excellent thermal shock stability ,Small thermal expansion coefficient,it is only 5.5×10-7/ºC
8.Control in less than 20 PPM, 15 PPM, 10 PPM, 5 PPM ,2 PPM.
