Catalog Number - 9502S-35-B

Provide reliable autosampler performance and compatibility with automated systems using Robo style screw caps designed for efficient workflows.

9502S-35-B caps feature a smooth‑sided, soft polypropylene design optimized for robotic capping and decapping systems, while also allowing easy manual handling. The silicone rubber / PTFE septa offers a dependable balance of chemical resistance and flexibility, supporting a wide range of HPLC and LC‑MS applications.

The pre‑slit septa allows easier needle penetration and helps prevent “septa plunge” into the vial during injection, improving autosampler consistency and reducing potential sample disruption. The PTFE layer provides inertness and minimizes analyte interaction, while the silicone backing supports resealability for repeated injections. These caps are comparable to Thermo™ / National Scientific DP® caps.
