DESCRIPTION
These 2 mL HPLC vial closures feature black polypropylene (PP) screw caps with an 8-425 thread finish, equipped with PTFE /silicone plain septa. Ideal for use in HPLC, GC, and LC-MS applications, the chemically inert PTFE liner resists solvents, while the silicone backing ensures resealability and low extractables. The plain septa (non-slit) provide a reliable seal for applications that do not require needle penetration. Designed for compatibility with 8 mm screw-thread vials, each pack includes 100 closures for consistent performance in analytical laboratories.
