CUSTOM ITEM: Caps, Screw Top, with Silicone Rubber / PTFE Pre-Slit Septa, fitted in smooth sided, Robo Style, soft polypropylene, Black Caps. For use with 9-425mm thread, 12x32mm autosampler vials. MICROSOLV Brand. 1000/CS. BULK PRICING.
Additional Info:
Support high‑volume and automated workflows with Robo style screw caps engineered for consistent autosampler performance and efficient handling.
9502S-35-K-M caps feature a smooth‑sided, soft polypropylene construction optimized for robotic capping and decapping systems while remaining easy to use manually. The silicone rubber / PTFE septa provides dependable chemical resistance and flexibility, making these caps suitable for a wide range of HPLC and LC‑MS applications.
The pre‑slit septa design allows smooth needle penetration and helps prevent “septa plunge” into the vial during injection. This improves injection consistency and maintains septa position during repeated analyses, making these caps a reliable choice for high‑throughput workflows. Comparable to Thermo™ / National Scientific DP® caps.
