Product Description

Borosilicate glass tubing 3.3 

Properties:
High chemical resistance : borosilicate glass 3.3 is very resistant to water, neutral and acid solutions, strong acids and their compounds.
 
Outstanding transmission:  borosilicate glass 3.3 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): 3-400mm

Wall thickness(WT): 0.4-13mm

Length(L): 1200-2000

Applications:
Due to its thermal shock resistance, chemical resistance and easily processed features, borosilicate glass tube 3.3 is widely used in laboratory devices, chemical equipment, solar thermal collector, kitchen ware and giftware.

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
