Precision Glass Tube with Low Expansion Coefficient

Low Boron Silicate Pharmaceutical Glass Tube 1. Product Overview Pharmaceutical packaging manufacturers and drug factories often face critical hidden dangers brought by inferior glass raw materials: ordinary glass tubing has unstable chemical inertness, poor resistance to water and acid erosion. When loaded with injections, lyophilized powder and oral liquid preparations, heavy metal ions will precipitate, causing liquid turbidity, pH fluctuation and batch inspection failure, which leads to high scrap loss and drug compliance risks. Many clients once replaced batches of unqualified glass tubes at extra cost to pass pharmacopoeia testing. Our low boron silicate pharmaceutical glass tube solves the core safety pain point of medical packaging fundamentally. With fixed boron content of 7.2, it achieves dual Grade 1 particle water resistance and surface water resistance as well as Grade 1 acid resistance; its linear expansion coefficient reaches 7.0×10⁻⁶ /℃ and annealing point hits 510℃.…
