Catalog Number - 9512C-0CV-T

The 9512C‑0CV‑T AQ™ Brand MRQ™ Snap‑Top Autosampler Vial is a 1.2 mL clear glass vial designed for chromatographic applications where maximum sample recovery and precise vial geometry are essential. These vials are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass, providing dependable chemical durability for routine through advanced analytical workflows.

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

Bottom depths are meticulously designed and QC‑controlled to prevent needles from contacting the vial bottom, ensuring compatibility with critical autosamplers and protecting injection hardware. A Certificate of Conformance (CoC) is available upon request.

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.
