Catalog Number - 9512C-0CV-T-RS

The 9512C‑0CV‑T‑RS MRQ™ Snap‑Top Autosampler Vial is a 1.2 mL clear glass vial engineered for chromatographic workflows where maximum sample recovery, low adsorption, and consistent vial geometry are critical. These vials are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass with Reduced Surface Activity (RSA) to minimize analyte interaction.

The MRQ™ (Maximum Recovery Quality) design features smooth internal walls with no ledges and a center‑draining conical bottom with a well slightly larger than typical autosampler needles. This geometry supports bottom‑entry needles and enables residual volumes as low as ~2 µL, helping recover the maximum usable sample from limited volumes.

Bottom depths are precisely designed and QC‑controlled to prevent needles from contacting the vial bottom, ensuring compatibility with critical and sensitive autosampler systems. This attention to geometry supports both recovery performance and needle safety.

Reduced surface activity is tested and certified for every production lot, ensuring consistent glass chemistry from batch to batch and vial to vial. A Certificate of Conformance (CoC) is available upon request. This vial is a popular choice for low‑abundance and pH‑sensitive analytes where surface interactions can impact results.

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 properly matched caps and septa are generally preferred to reduce evaporation and maintain sample integrity.
