Product Description

 

Product Description

1.High temperature Transparent Factory Customized Heat Resistance Round Bottom Quartz Glass Test Tube for lab test
2.Quartz glass tube is laboratory instruments and utensil

Thermal Properties of clear quartz glass test tube:

The coefficient of thermal expansion of quartz glass is small, only one-twelfth to one-twentieth of the ordinary glass times, the standard stipulates that the specimen will be burned to 1200 degrees Celsius and then cast sharply into cold water, repeatedly more than three times is not allowed to blow up.

 

Application of quartz glass pipe:

 

1) Electric light source

 

2) Electronics industry

 

3) laser

 

4) Aerospace (wide transmittance from ULTRAVIOLET to infrared)

 

5) Heating industry

 

6) Fabrication of optical fiber (with very low spectral loss)

 

7) Laboratory instruments and utensils (high temperature and corrosion resistance)
