CTD-0900-RS - VIALS 1.2ml MRQ Screw 9mm Clear 100/pk

The CTD-0900-RS MRQ™ Autosampler Vial is a precision‑engineered, low‑residual‑volume vial designed for maximum analyte recovery, injection reliability, and reproducibility. Manufactured from first hydrolytic, Class A, Type‑33 reduced surface activity borosilicate glass, MRQ™ vials virtually eliminate adsorption of basic compounds commonly observed with standard borosilicate glass.

With a nominal fill volume of 1.2 mL, MRQ™ vials are optimized for low‑volume and low‑dosage applications where every microliter matters. The vial’s smooth, ledge‑free internal geometry and conical bottom provide true center‑draining behavior, improving recovery and eliminating dead zones found in competitive designs.

Key Features

RSA™ Reduced Surface Activity Glass

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

• Virtually no adsorption of basic compounds

• Certified reduced surface activity for analyte integrity

Low Residual Volume, High Recovery Design

• 1.2 mL fill volume optimized for low‑dosage samples

• Smooth internal walls with no ledges

• Conical bottom promotes efficient center draining

• Maximizes recovery for valuable and low‑abundance analytes

Precision MRQ™ Well Geometry

• Well opening slightly larger than autosampler needles

• Compatible with side‑entry port needles

• Designed for complete and repeatable sample aspiration

• Improves consistency across demanding autosampler platforms

Needle Safety and Injection Reliability

• Bottom depths precisely designed and QC controlled

• Prevents needles from striking the vial bottom

• Reduces missed injections and instrument wear

• Compatible with high‑performance and high‑throughput autosamplers

Why Choose MRQ™ Vials?

MRQ™ vials combine RSA™ glass chemistry with precision mechanical design to solve the most common sources of injection variability:

• Inconsistent sample recovery

• Adsorption of basic or polar analytes

• Missed or incomplete injections

• Autosampler needle damage

Batch‑to‑batch and vial‑to‑vial consistency make MRQ™ vials an excellent choice for routine and regulated workflows, particularly where low‑dosage pharmaceutical formulations or trace‑level analysis are required.

Each production lot is tested and certified for reduced surface activity. A Certificate of Conformance is available upon request.

Typical Applications

• Low‑dosage pharmaceutical formulations

• Low‑abundance and trace‑level analytes

• pH‑sensitive and basic compounds

• LC‑MS and UHPLC autosampling

• High‑precision, high‑throughput analytical workflows
