CUSTOM ITEM: Caps, Screw Top, with Silicone Rubber / PTFE, low durometer Septa, bonded in "knurled", polypropylene, Black Caps. For use with 9-425mm thread, 12x32mm autosampler vials. MICROSOLV Brand. 100/PK.
Additional Info:
Provide reliable sealing and consistent performance with screw top caps designed for HPLC workflows and general autosampler use.
9502S-10C-BLK caps feature a durable knurled polypropylene design for improved grip and easy handling during manual or automated workflows. The bonded silicone rubber / PTFE septa combines chemical resistance from the PTFE layer with the flexibility of silicone, offering dependable sealing and support for repeated needle penetrations.
The septa is non‑slit, which enhances sealing integrity prior to injection and helps minimize evaporation or contamination during storage. The low durometer silicone provides easier needle penetration compared to harder septa, while still maintaining effective resealing performance in most applications.
