Always Check for Container-Closure Discoloration During Stability

Understanding the Tip: Why visual inspection is critical in container-closure systems: Visual assessment of packaging components is often the first indicator of underlying chemical instability or material interaction. Discoloration of caps, seals, stoppers, or vial interiors may signal oxidation, leachables migration, UV damage, or reactions between the product and packaging. Regular inspection of container-closure systems…
