Catalog Number - 9509S-3DCP-PX

Maximize recovery and injection consistency for challenging analytes with RSA‑Pro X™ hydrophobic vial kits designed for high‑sensitivity LC‑MS workflows.

9509S‑3DCP‑PX kits utilize RSA‑Pro X™ surface treatment to create a highly stable hydrophobic barrier that prevents adsorption of “sticky” compounds to the glass surface. Unlike traditional silanized vials, this treatment remains effective even in aqueous environments, providing long‑term stability and consistent recovery for proteins, peptides, enzymes, and trace‑level unknowns.

These Easy Purchase Packs also improve lab efficiency by combining vials and caps into a single SKU. This eliminates compatibility issues, reduces purchasing complexity, and prevents stock imbalances between closures and vials. The included AQR™ pre‑slit septa caps provide ultra‑low extractables and improved injection performance by reducing coring and ensuring consistent needle penetration across repeated analyses.
