Additional Info:
The 9509C‑WAV‑RS RSA brand Snap‑Top Autosampler Vial is a 2 mL amber glass vial designed for chromatographic applications where low analyte adsorption, light protection, and consistent glass chemistry are important. Manufactured from first hydrolytic, Class A, Type N51A borosilicate glass, these vials are amberized and engineered with Reduced Surface Activity (RSA®) to minimize surface interactions that can affect sensitive analytes.
Integrated ceramic write‑on patches and fill lines provide durable labeling and volume reference that resist smearing or scratching when exposed to common laboratory solvents. This supports clear identification and handling in both routine and documentation‑driven laboratory workflows.
Bottom depths and vial heights are tightly designed and QC‑controlled to support maximum sample recovery while protecting autosampler needles. The glass chemistry does not introduce sodium ions or other species that can cause pH changes, making these vials well suited for low‑abundance and pH‑sensitive compounds.
Reduced surface activity is tested and certified for each production lot, ensuring consistent performance from batch to batch and vial to vial. This vial is a popular amber option within the RSA® snap‑top family for applications requiring adsorption control and light protection.
Important Use Guidance Snap caps and snap‑top vials are not generally recommended for LC‑MS applications or other critical analyses involving volatile solvents, including aqueous systems. For these applications, screw‑thread vials with matched caps and septa are recommended to reduce solvent evaporation and maintain sample integrity.
