Cyralux™ 20 mm Sterile Ready-to-Use (RTU) Serum Stoppers are pharmaceutical-grade bromobutyl rubber closures designed for 20 mm crimp-finish injection vials. Supplied washed, siliconized, sterilized, and ready for use, these stoppers help simplify aseptic filling operations by eliminating the need for in-house stopper washing and siliconization.
Made from halobutyl (bromobutyl) elastomer, Cyralux™ serum stoppers are designed to provide reliable sealing, consistent needle access, and self-sealing performance for liquid-fill applications. Their controlled flange supports consistent crimp seating and seal performance.
