Glass Tubing Compositions

51 Expansion Borosilicate Glass Tubing is the global standard for injectable pharmaceutical primary packaging products. The glass is designed as the long term storage solution for pharmaceuticals with the unique ability to stay chemically inert, while maintaining the integrity and stability of pharmaceutical preparations.   

Corning® 51 is produced by Corning on three continents.  It has decades of documented industry leading performance and is qualified as the material of choice for customers providing ampoules, vials, syringes, and cartridges to the global pharmaceutical industry. Corning® 51 Glass Tubing complies with international pharmacopoeia standards including EU, USP, JP and YBB.

33 Expansion Borosilicate Glass Tubing is the North American standard for glass vial products for pharmaceutical injectable preparations and is the material of choice for NA vial converters. This versatile glass is the highest standard laboratory glass of the borosilicate variety with an ASTM E 438 classification of A.  

Corning® 33 Glass is produced exclusively at our Vineland, NJ, USA facility, where we operate the world’s largest 33 expansion pharmaceutical tubing furnace. This composition has key characteristics for the pharmaceutical and adjacent industries where chemical durability and depyrogenation require a more robust borosilicate class material.

Originally designed for Laboratory apparatus and adopted as the North American Standard for vials, a Corning® 33 Glass produced vial will stay chemically inert, while maintaining the integrity and stability of pharmaceutical preparations. Corning 33 Glass Tubing complies with international pharmacopoeia standards (EU, USP, JP and YBB) when used as the raw material for vial products.

51 Expansion Borosilicate Amber Glass tubing is the global standard for primary packaging for pharmaceutical products for injection where Ultra Violet light protection is required for light sensitive applications.  The glass has the ability to stay chemically inert, while maintaining the integrity and stability of its contents. The addition of iron and titania coloring agents enhance the Amber material characteristics so the final containers spectral transmission exceeds the UV blocking requirement of both the US and EU Pharmacopoeia.

Corning® 51 Amber is produced by Corning on three continents.  Corning® 51 Amber Tubing complies with international pharmacopoeia standards including EU, USP, JP and YBB for both chemical durability and light transmission.

Corning’s boron free, aluminosilicate clear glass was specifically designed as the base material for Corning® Valor® Glass Vials. The glass is a patented formula that was designed to be chemically strengthened after vial conversion by subjecting the vials to a potassium nitrate bath. This process effectively exchanges the sodium ions on the glass surface with potassium ions. The resulting glass structure produces a vial with superior mechanical strength and enhanced chemical durability.

After treatment, the glass meets updated USP 660 requirements for a Type I glass. Corning’s Valor Glass vials exhibits equivalent or better extractable testing concentrations against a wide range of pHs compared to conventional borosilicate glass. Corning's aluminosilicate tubing easily converters to a vial on industry standard machines with similar working ranges and a coefficient of linear expansion CLTE or CTE of 68.
