The MSBS-9 9mm Blue Screw Bonded Pre-Slit Cap Septa is designed for chromatography laboratories requiring dependable sealing and consistent autosampler performance. Manufactured with a durable 9mm blue polypropylene screw cap and a permanently bonded PTFE/Silicone pre-slit septum, it minimizes coring while allowing smooth, repeated needle penetration. The chemically inert PTFE layer provides excellent resistance to solvents and sample contamination, while the silicone backing ensures superior resealing after multiple injections. Its bonded construction prevents septum displacement, making it ideal for automated HPLC, UHPLC, and GC workflows requiring accurate, reproducible analytical results.
