HM Customized Low Thermal Expansion Pyrex Glass Tube

 

 

Product Description

 

 

Properties:

  1. High temperature resistant, Borosilicate glass tube can work in 500°C with long time. 
  2. Corrosion resistant, except hydrofluoric acid, Borosilicate glass tube do not react with any acid.
  3. Excellent thermal shock stability making them more dimensionally stable.
  4. High transmission to 85%
  5. Electric insulation ,it is 10000 times of usual glass.
  6. Low thermal expansion.
