Catalog Number - 9509S-10C-B-M

The 9509S‑10C‑B‑M AQR™ Screw Caps are engineered for high‑purity chromatographic applications, offering exceptional chemical inertness and ultra‑low background interference for demanding analytical work.

These caps feature non‑pigmented silicone rubber/PTFE septa, eliminating dyes and additives that can contribute to contamination, ensuring maximum signal integrity for LC‑MS, LC‑MS/MS, and GC‑MS workflows.

Designed for 9‑425 thread, 12 × 32 mm autosampler vials, each cap is constructed with a knurled polypropylene closure to provide secure sealing and reliable handling, making them ideal for high‑throughput laboratory environments.
