Catalog Number - 9509S-1XWCP-RS

Reduced Surface Activity for Better Data Integrity

RSA™ (Reduced Surface Activity) vials are engineered to minimize analyte adsorption to glass surfaces, helping preserve sample integrity for low‑level or adsorption‑prone compounds. This makes the 9509S‑1XWCP‑RS well suited for routine and regulated chromatographic applications where consistent recovery and reproducibility are required.

The clear borosilicate glass construction allows visual confirmation of sample volume, clarity, and particulates while maintaining low extractables and chemical inertness during autosampler residence.

Silicone / PTFE Septa for Reliable Sealing and Chemical Resistance

The included blue screw caps are fitted with silicone rubber / PTFE septa, providing a chemically resistant barrier between the sample and the cap. This configuration supports clean needle penetration and dependable resealing for standard autosampler workflows and repeated injections.

The bonded septa construction ensures consistent septum positioning, reducing the risk of leaks, coring, or variability during analysis.

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 simplifying bench setup and inventory control.
