Additional Info:
Reduced Surface Activity for Better Data Integrity
RSA™ (Reduced Surface Activity) vials are engineered to reduce analyte adsorption to glass surfaces, helping maintain accurate and reproducible results for low‑level or adsorption‑sensitive compounds. The 9509S‑9WCP‑RS is well suited for LC‑MS and LC‑MS/MS workflows where sample integrity and low background contribution are essential.
The clear borosilicate glass allows direct visual confirmation of sample condition and volume while maintaining low extractables and chemical inertness during autosampler residence.
Single‑Injection Caps with Thinned Penetration Point for LC‑MS/MS
The included natural‑color screw caps are designed for single‑injection use and feature a thinned penetration point to support clean, controlled needle entry. This design minimizes septum material contribution and is optimized for LC‑MS/MS applications where low bleed and minimal contamination are critical.
These caps are intended for one‑time injections and are not designed for resealing or repeated punctures, helping maintain consistent injection performance in sensitive mass spectrometry workflows.
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 setup at the bench.
