Zinc detected in clogged syringes

Paul Scherrer Institute
Peer-Reviewed Publication

Employees of the technology transfer centre ANAXAM and researchers from the Paul Scherrer Institute PSI used the unique analytical methods available at PSI to look inside pre-filled syringes. They found that, in rare cases, zinc from the needle shield can leach into the drug solution to be injected and possibly contribute to syringe clogging.
