Catalog Number - 9509S-3EWAP-RS

Reduced Surface Activity for Better Data Integrity

RSA™ (Reduced Surface Activity) vials are specifically engineered to reduce analyte adsorption to glass surfaces, helping preserve low‑level or adsorption‑prone compounds. This makes the 9509S‑3EWAP‑RS ideal for trace analysis, polar compounds, and LC‑MS/MS applications where sample integrity is critical.

The amber glass provides additional protection for light‑sensitive analytes, improving stability during autosampler residence and extended run sequences.

Pre‑Slit Soft‑Guard Septa for High‑Throughput Operation

The included blue screw caps are fitted with white silicone rubber / red PTFE pre‑slit Soft‑Guard septa, combining gentle needle penetration with reduced coring and septum wear. This configuration supports rapid, repeat injections while maintaining reliable resealing performance.

Compatible with Waters Alliance™ and ACQUITY™ UPLC® systems, as well as any autosampler or instrument platform that requires a pre‑slit septa for reliable needle penetration and high‑throughput operation.

Easy Purchase Pack Convenience

Easy Purchase Packs are a convenient way to order and inventory autosampler vials with their matching caps. The reclosable kit packaging keeps vial and cap types matched, organized, and clean, minimizing handling errors and saving setup time at the bench.
