Westar Ready-to-Use (RU) steam-sterilized plungers can mitigate risk for chemical and physical deterioration of the component through an optimized steam sterilization cycle that, when compared to high-dose gamma irradiation, may: Minimize impact on the elastomers' physical characteristics, and on chemical oxidation and degradation during the plunger's shelf-life; decrease the numbers 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.
