Catalog Number - 9502S-30C-BL-M

Support high‑volume workflows with screw top caps designed to improve injection reliability and consistency in autosampler applications.

9502S-30C-BL-M caps feature a bonded silicone rubber / PTFE pre‑slit septa, permanently affixed to the cap to prevent “septa plunge” into the vial during injection. This design enhances autosampler performance by maintaining septa position and ensuring consistent needle penetration, especially important in repetitive, high‑throughput analyses.

The pre‑slit septa reduces needle resistance and improves injection reproducibility, while the PTFE layer provides chemical resistance and inertness. The knurled polypropylene cap design ensures a secure grip for efficient handling during large batch operations. These caps are specifically designed for compatibility with Waters® Alliance and Acquity autosamplers.
