Bubble testing remains a simple and practical method for visual leak detection in pharmaceutical packaging. By exposing containers to a pressurized environment and observing the formation of bubbles, this technique identifies openings that allow gas to escape. Though less sensitive than modern deterministic methods, bubble testing serves as a useful preliminary inspection, training tool, and quick QC check. For small‑scale testing or secondary verification, bubble testing helps quality teams screen containers before further analysis. Discover how it fits into a broader leak detection strategy for pharmaceutical packaging.
