Black 8-425 Open Top Screw Closures:
High-Integrity Closures for 2mL Autosampler Vials in HPLC & GC Applications
The Black 8-425 Open Top Screw Closures are expertly designed for use with 2mL 8-425 threaded autosampler vials, providing secure, high-performance sealing for precision laboratory analysis. Each closure features a built-in PTFE/silicone pre-slit septum, allowing for direct needle penetration during automated sampling without the need for manual cap removal.
Crafted from premium-grade materials, these closures offer excellent chemical resistance, tight sealing, and thermal stability, effectively preventing sample contamination, evaporation, and degradation. Their robust construction and compatibility with automated systems make them a trusted choice in high-throughput laboratories conducting HPLC (High-Performance Liquid Chromatography) and GC (Gas Chromatography) testing.
