Glass delamination remains a significant concern for the storage of biologics. This is especially the case for large molecule formulations with high pH levels.

The particle laboratory can perform glass delamination testing using Differential Interference Contrast Microscopy (DICM) to determine if glass delamination has the potential to occur on selected glass.

In addition, the particle laboratory has the capability to perform particle counting and sizing for sub-visible and visible particles using:
