CUSTOM ITEM: Caps, Screw Top, with Natural Silicone Rubber / White PTFE Septa, bonded in "knurled", polypropylene, Blue Caps. For use with 9-425 thread, 12x32mm autosampler vials. MICROSOLV Brand. 100/PK.
Additional Info:
Provide reliable sealing and cost efficiency with bonded septa screw caps designed for routine analytical workflows.
9502S-11-CB caps are manufactured with a knurled polypropylene design for improved grip and ease of handling during manual capping and removal. The bonded natural silicone rubber / PTFE septa offers a durable, integrated sealing system that combines chemical resistance with consistent resealing performance for repeated injections.
Natural silicone rubber is produced without added color and offers the same performance characteristics as white silicone while providing a more economical option. The PTFE layer ensures chemical inertness and low extractables, making these caps suitable for a wide range of HPLC and LC‑MS applications.
