Key Specifications

Key Specifications of Insulin Cartridge Glass Classification: It is classified as USP Type I (also known as neutral borosilicate glass), which represents the highest level of hydrolytic resistance.

Composition:

It typically contains approximately 70–80% silica and is enriched with boron trioxide and aluminium oxide to enhance its durability and non-reactive properties. Standards: Manufacturing adheres to global pharmacopeia standards such as USP <660> and EP 3.2.1, as well as international standards like ISO 13926-1 for cartridge dimensions. Why This Glass is Used Chemical Inertness: Borosilicate glass is non-reactive, which prevents interaction between the insulin and the container, ensuring the medication's stability and efficacy over its shelf life.

Precision and Dosing:

It provides high dimensional stability, allowing for precise plunger movement that is critical for accurate insulin dosing. Transparency: Its optical clarity allows patients and healthcare providers to easily inspect the insulin for particles, discoloration, or the remaining volume.

The glass can withstand high-temperature sterilization processes, such as autoclaving or steam sterilization, without cracking or deforming.
