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. BULK PRICING.
Additional Info:
Designed for automated and high‑throughput workflows, these Robo style screw caps provide consistent performance and efficient handling in autosampler applications.
9502S-35-K caps feature a smooth‑sided, soft polypropylene construction that supports robotic capping and decapping systems while remaining easy to use manually. The silicone rubber / PTFE septa provides a reliable balance of flexibility and chemical resistance, ensuring compatibility with a wide range of HPLC and LC‑MS applications.
The pre‑slit septa design allows easier needle penetration and helps prevent “septa plunge” into the vial during injection. This improves autosampler reliability, enhances injection consistency, and reduces disruption to the sample during repeated analyses. These caps are comparable to Thermo™ / National Scientific DP® caps commonly used in automated workflows.
