Catalog Number - 9512S-0CV-T

The 9512S‑0CV‑T MRQ™ Autosampler Vial is the standard MRQ™ precision vial, engineered to deliver exceptional recovery, injection reliability, and visibility using high‑quality Type‑33 borosilicate glass. It shares the same MRQ™ geometry used across the MRQ product family, providing ultra‑low residual volume and consistent performance across modern autosamplers.

With a nominal fill volume of 1.2 mL and a residual volume as low as ~2 µL, MRQ™ vials are ideal for applications where sample efficiency and injection repeatability are critical. The vial’s smooth, ledge‑free internal walls, combined with a conical bottom and precision well, provide true center‑draining behavior and reliable sample recovery.

Key Features

Precision MRQ™ Geometry

• Smooth internal walls with no ledges

• Conical bottom promotes center draining

• Residual volume as low as ~2 µL

• Minimizes sample loss in low‑volume workflows

Optimized Well Design

• Well diameter slightly larger than autosampler needles

• Designed for bottom‑entry needle systems

• Supports consistent, repeatable sample aspiration

Needle Safety and Injection Reliability

• Bottom depths precisely designed and QC controlled

• Reduces risk of needle strikes

• Compatible with demanding autosamplers

High‑Quality Type‑33 Glass

• First hydrolytic, Class A borosilicate glass

• Excellent clarity for sample visibility

• Suitable for routine and regulated analytical workflows

How This MRQ™ Vial Compares to Other MRQ™ Options

All MRQ™ vials share the same ultra‑low‑residual‑volume geometry. The difference between SKUs lies in glass surface chemistry, not mechanical design.

9512S‑0CV‑T (This Product – Standard MRQ™)

• Untreated Type‑33 borosilicate glass

• Best choice for general‑purpose MRQ™ applications

• Ideal when adsorption is not a concern and maximum value is desired

9512S‑0CV‑TD (Deactivated MRQ™)

• Chemically deactivated (silanized) Type‑33 glass

• Reduces adsorption of surface‑active or basic analytes

• Selected when methods specify deactivated glass

9512S‑0CV‑T‑RS (RSA™ MRQ™)

• RSA™ Reduced Surface Activity glass

• Inherently eliminates surface silanols—no silanization

• Provides the highest level of surface stability and reproducibility

• Preferred for low‑dosage pharmaceuticals, trace analysis, and regulated workflows

In summary:

• Choose 9512S‑0CV‑T for standard MRQ™ performance and value

• Upgrade to ‑TD when deactivated glass is required

• Choose ‑T‑RS for the most demanding recovery and compliance‑driven applications

Typical Applications

• Routine LC and LC‑MS autosampling

• Low‑volume injections

• High‑throughput analytical workflows

• Sample‑limited methods where recovery matters
