Parenteral Packaging Challenges? Our Glass Expertise Can Help!

Drug formulations, including water for injection, can be stored safely thanks to the excellent barrier properties of glass. FIOLAX® is a borosilicate glass tubing with low alkali content that reduces alkali borate appearance. This offers impressive hydrolytic and chemical glass resistance, minimizing the risk of drug container interactions.

The tubing product line FIOLAX® clear CHR is beneficial for highly demanding formulations. These formulations are sensitive to extractables such as sodium in pH-sensitive / unbuffered formulations. Here, hydrolytic resistance of the inner glass surface along with glass grains is monitored.

Lyophilization, or freeze-drying, preserves injectable drugs by removing water. This is a demanding procedure as the parenteral container is frozen from inside and at the same time heated from the bottom. A container made of FIOLAX® tubing (CTE of 4.9) can bear a temperature difference of almost 200°C and therefore has optimal temperature shock resistance.

Also, did you know that internal pressure during lyophilization challenges the strength of the glass, and any surface defects can further weaken it? Our product line FIOLAX® clear with Optimized Strength (OS) tubing is developed with special attention to avoid surface defects.

In pharmaceuticals, every microgram counts. SCHOTT’s FIOLAX® glass tubing, enhanced by the perfeXion® quality process, ensures precise geometry and 100% inspection of every tube.
This guarantees unmatched dimensional accuracy and flawless cosmetic quality, critical for safe and effective drug delivery. Whether used in vials, ampoules, syringes, or cartridges, this high-quality Type I borosilicate glass tubing minimizes the risk of dosing errors and safeguards container integrity. By eliminating defects such as airlines and wall thickness variations, FIOLAX® supports consistent dosing and sterility—critical for sensitive biologics and injectable therapies.
