West Pharmaceutical Services: Steam-sterilized plungers

Westar® Ready-to-Use (RU) steam-sterilized plungers can mitigate risk for chemical and physical deterioration of plungers.

Pw 1783 West Elas S Tbag 009

When compared to high-dose gamma irradiation, steam-sterilized plungers may minimize impact on elastomers’ physical characteristics and on chemical oxidation and degradation, decrease the number and lower the levels of extractables, with less potential for interaction between the plunger and the drug, and improve prefilled syringe functionality due to lower and more consistent break loose forces.
