Additional Info:
The 9509C‑WCV‑RS RSA Brand Snap‑Top Autosampler Vial is a 2 mL clear glass vial engineered for chromatographic applications where glass chemistry consistency and low analyte interaction are critical. Manufactured from first hydrolytic, Class A, Type 33 borosilicate glass, these vials feature Reduced Surface Activity (RSA®) to minimize adsorption that can affect sensitive compounds.
Integrated ceramic write‑on patches and fill lines provide durable labeling and clear volume reference that resist smearing or scratching when exposed to common laboratory solvents. This makes the vial well suited for routine handling, documentation‑driven workflows, and regulated environments.
Bottom depths and vial heights are tightly designed and QC‑controlled to support maximum recovery while protecting autosampler needles. The glass chemistry does not introduce sodium ions or surface interactions that can cause pH shifts, making these vials suitable for low‑abundance and pH‑sensitive analytes.
Reduced surface activity is tested and certified for every production lot, ensuring consistent performance from batch to batch and vial to vial. For this reason, this product is the most widely used 2 mL snap‑top vial in the RSA® portfolio for applications where adsorption control is required.
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.
