Cyralux™ 13 mm Sterile Ready-to-Use (RTU) Serum Stoppers are pharmaceutical-grade, latex-free bromobutyl rubber closures for 13 mm crimp-neck injection vials, including typical 2R and 3 mL formats. Designed for liquid-filled injectable products, the solid-plug construction provides controlled flange seating, reliable needle access, and self-sealing performance. Each stopper is washed with WFI-grade water, siliconized, 100% vision inspected, and supplied terminally sterilized in double-bagged sterile-barrier packaging. The plug geometry accommodates European blowback, North American blowback, and straight-wall ISO vials. Suitable for aseptic filling workflows, these closures support consistent processing and documented lot traceability.
