Catalog Number - 9512S-0CV-RS

The 9512S‑0CV‑RS Max Recovery™ Autosampler Vial is a market‑leading 1.8 mL center‑draining vial engineered for laboratories that require maximum analyte recovery at standard autosampler volumes. Unlike MRQ™ vials, this product uses a distinct internal geometry optimized specifically for full‑volume injections while maintaining low residual volume and excellent autosampler compatibility.

Manufactured from first hydrolytic, Class A, Type‑33 reduced surface activity borosilicate glass, this vial minimizes analyte interaction with the glass surface. The smooth, ledge‑free internal walls and conical bottom promote true center draining, allowing bottom‑entry needle designs to recover the maximum amount of sample during each injection.

Key Features

RSA™ Reduced Surface Activity Glass

• First hydrolytic, Class A, Type‑33 borosilicate glass

• RSA™ technology removes active surface silanols

• Virtually no adsorption of basic or polar analytes

• Each lot tested and certified for reduced surface activity

Max Recovery™ Center‑Draining Geometry

• Nominal fill volume: 1.8 mL

• Residual volume as low as ~8 µL

• Smooth internal walls with no ledges

• Conical bottom supports efficient center draining

Autosampler Needle Safety

• Bottom depths precisely designed and QC controlled

• Prevents needle strikes in critical autosamplers

• Supports consistent injection performance

• Suitable for high‑throughput and demanding systems

Why Choose a Max Recovery™ Vial?

Max Recovery™ autosampler vials are designed for workflows that require maximum recovery at conventional autosampler sample volumes, without transitioning to narrow wells or micro‑volume designs.

This vial is especially popular because it delivers:

• High recovery without sacrificing sample volume flexibility

• Consistent performance vial‑to‑vial and lot‑to‑lot

• Broad compatibility with standard autosampler hardware

The combination of RSA™ glass chemistry and center‑draining geometry makes this a trusted choice for routine, regulated, and LC‑MS workflows.

Important Geometry Note

This vial does not share the same geometry as MRQ™ vials.

• MRQ™ vials are optimized for micro‑volume recovery using a precision well

• Max Recovery™ vials are optimized for full‑volume injections with a wide, center‑draining base

Both designs serve different analytical needs and should be selected based on sample volume and autosampler strategy, not as direct equivalents.

Typical Applications

• Low‑abundance analytes

• pH‑sensitive compounds

• LC‑MS and UHPLC autosampling

• Routine and regulated analytical workflows

• Applications requiring high recovery at standard vial volumes
