Catalog Number - 9509S-3XWCP-RS

Reduced Surface Activity for Better Data Integrity

RSA™ (Reduced Surface Activity) vials are engineered to reduce analyte adsorption to glass surfaces, helping maintain accurate concentration levels for low‑level or adsorption‑sensitive compounds. The 9509S‑3XWCP‑RS is well suited for routine and high‑throughput chromatographic workflows where reproducibility and data integrity are critical.

The clear borosilicate glass construction allows direct visual inspection of sample volume and condition while maintaining low extractables and chemical inertness during autosampler residence.

Pre‑Slit Silicone / PTFE Septa for High‑Throughput Operation

The included blue screw caps are fitted with silicone rubber / PTFE pre‑slit septa, designed to support smooth, reliable needle penetration while minimizing septum coring and wear. This configuration is ideal for high‑throughput autosampler operation and repeated injections.

Bonded septa construction ensures consistent septum positioning and reliable resealing, helping reduce injection variability and extend cap usable life during demanding analytical sequences.

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.
