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. Compared to other low volume vials, these are virtually indestructible

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
