Comparative Leachable Study of Glass Vials to Demonstrate the Impact of Low Fill Volume.

The pharmacopeia method for measuring the chemical durability of parenteral glass packaging is the hydrolytic resistance test in which the vial is filled to 90% of its brimful volume as described, for example, in USP <660>. However, an increasing number of innovative drugs are filled significantly below the nominal volume of the vial. As a consequence, the determined hydrolytic resistance is not representative of the concentrations of leached "glass" elements for low fill volumes.

A quick test to monitor the delamination propensity of glass containers.

Unlabelled: Glass delamination has developed as a quality problem for primary packaging containers over the last years. Beside other factors the container production process can contribute to this phenomenon, and it seems mandatory to steer and control the critical parameters. With the Schott Delamination Quicktest, a rapid test method is developed that provides a rough measure for the container-related properties that affect delamination risk in a simple and reliable manner and in a relatively short time span.
