Vials, Screw Top, Glass. Amber, 2ml, with Write-On Patch and fill lines, Surface Treated, 9-425mm threads, 12x32mm outer dimensions. For use as an autosampler vial or storage bottle. RSA-Pro Brand. 100/PK.
Additional Info:
The 9509S‑WDAV‑MR RSA‑Pro™ Amber Screw‑Top Autosampler Vial is a highly specialized 2 mL vial engineered for light‑sensitive compounds, low‑abundance analytes, proteins, and peptides. Manufactured from first hydrolytic, Class A, Type N51A amberized borosilicate glass, each vial undergoes an advanced surface‑treatment process to deliver enhanced hydrophobicity and certified reduced surface activity.
This unique combination of RSA glass chemistry plus surface treatment provides more complete and consistent deactivation than conventional silanized vials. The amber glass further protects photosensitive samples while preserving analyte integrity throughout storage and analysis.

Why Choose RSA‑Pro™ Amber Vials?
RSA‑Pro™ amber vials are designed for workflows where surface chemistry control and light protection are critical. Unlike basic surface‑modified or silanized vials, RSA‑Pro™ vials offer:
Complete and uniform deactivation
Excellent lot‑to‑lot and vial‑to‑vial consistency
Reliable performance with adsorption‑prone compounds
This makes them a preferred choice for bioanalytical, pharmaceutical, and LC‑MS laboratories handling sensitive analytes.
Typical Applications
Proteins and peptides
Low‑abundance and adsorption‑prone analytes
Light‑sensitive compounds
LC‑MS and UHPLC workflows
Bioanalytical and pharmaceutical research
