Frequently Asked Questions (FAQs)

How does the coefficient of expansion of glass affect its suitability for pharmaceutical packaging?

The "thermal expansion coefficient" typically ranges between 5.0 × 10^-6 /°C and 10.0 × 10^-6 /°C, depending on the specific type of glass. This coefficient indicates the extent to which a unit length of glass will expand or contract with a one-degree change in temperature, expressed in terms of per degree Celsius (°C).

What does "glass hydrolytic resistance" mean?

In the context of glass used for pharmaceutical packaging, hydrolytic resistance is a crucial property. It indicates the glass's ability to maintain its integrity and prevent leaching of ions or other substances into the contained pharmaceutical product when in contact with water or aqueous solutions. Glass with high hydrolytic resistance is less prone to chemical interactions and is therefore preferred for packaging sensitive pharmaceutical formulations.

Why is amber-colored glass tubing used for pharmaceutical packaging?

Amber-colored glass tubing is often used to manufacture vials, ampoules, and bottles for packaging light-sensitive medications. The amber color of the glass provides protection against ultraviolet (UV) light, which is known to degrade light-sensitive pharmaceuticals, thus ensuring the stability and potency of the enclosed medications.
