Vials, Screw Top, Glass. Clear, 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‑WDCV‑MR RSA‑Pro™ Screw‑Top Autosampler Vial is a highly specialized 2 mL vial designed for low‑abundance analytes, proteins, and peptides where native glass or simple silanized products are insufficient. Manufactured from first hydrolytic, Class A, Type‑33 borosilicate glass, each vial is further surface treated to substantially increase hydrophobicity while maintaining certified reduced surface activity.
This two‑step approach — RSA glass chemistry combined with advanced surface treatment — delivers exceptional deactivation, consistency, and reproducibility. These vials are widely chosen for demanding LC‑MS, bioanalytical, and protein‑based workflows where analyte recovery and surface control are critical.
