Properties:
High chemical resistance: borosilicate glass 7.0 is very resistant to water, neutral and acid solutions, strong acids and their compounds.

Outstanding transmission: borosilicate glass 7.0 is very transparent, it has stable transmission from UV-A to IR range.

Resistant to thermal shock: it is perfect material in contact with fire and high temperatures due to its high working temperatures and thermal shock.

Dimensions range(mm)
Outside diameter(OD): 10.75mm & 14.75mm

Wall thickness(WT): 0.2-1.2mm

Length(L): 1200-2000mm

Applications:
Due to its thermal shock resistance, chemical resistance and easily processed features, borosilicate glass tube 7.0 is widely used in making vials for injection vials,vaccine  vials.

Support:
We have engineers with many years experience in glass tubing processing and special knowledge in glass properties and annealing practise. We can provide free advice and training.
