These spots are most likely the remnants of the vial forming process and are comprised of amber glass and trapped air. They are not a source of contamination.
When two different QC tests are run on these vials it verifies that these types of spots do not cause any adverse effects in performance. The results of both an HPLC test and an expert microscopy test point to no manufacturing defects.
