Catalog Number - 9512S-0CV-TD

The 9512S‑0CV‑TD MRQ™ Deactivated Autosampler Vial is designed for laboratories that require MRQ™ precision geometry combined with a deactivated internal surface. Manufactured from first hydrolytic, Class A, Type‑33 borosilicate glass, each vial is chemically deactivated (silanized) to reduce surface activity and improve recovery of adsorption‑prone analytes.

With a nominal fill volume of 1.2 mL and an exceptionally low residual volume (as low as ~2 µL), this vial is optimized for low‑volume workflows. The smooth, ledge‑free internal walls, conical bottom, and precision well slightly larger than autosampler needles provide consistent, center‑draining sample recovery.

Key Features

Deactivated MRQ™ Glass

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

• Chemically deactivated (silanized) surface

• Reduces adsorption of surface‑active and basic analytes

Low Residual Volume Design

• 1.2 mL fill volume

• Residual volume as low as ~2 µL

• Smooth internal walls with no ledges

• Conical bottom promotes center draining

Precision Well Geometry

• Well diameter slightly larger than autosampler needles

• Optimized for bottom‑entry needle designs

• Enables maximum sample aspiration and consistency

Needle Safety and Autosampler Compatibility

• Bottom depths precisely designed and QC controlled

• Helps prevent needle strikes

• Compatible with demanding, high‑precision autosamplers

How This Vial Differs from 9512S‑0CV‑T‑RS

Although both vials share the MRQ™ geometry and low‑residual‑volume design, the key difference is surface chemistry:

9512S‑0CV‑T‑RS (RSA™ MRQ™ Vial)

• Uses RSA™ Reduced Surface Activity glass

• Eliminates surface silanols at the glass chemistry level

• Provides near‑inert behavior without silanization

• Best choice for maximum reproducibility, lot‑to‑lot surface consistency, and regulated or low‑dosage pharmaceutical workflows

9512S‑0CV‑TD (Deactivated MRQ™ Vial)

• Uses chemically deactivated (silanized) Type‑33 glass

• Reduces surface activity via surface treatment

• Excellent choice for adsorption‑prone analytes where deactivated glass is specified

• Often selected when method requirements call for silanized glass rather than intrinsic RSA chemistry

In short:

• Choose 9512S‑0CV‑T‑RS for ultimate surface stability and RSA™ performance

• Choose 9512S‑0CV‑TD when a deactivated/silanized vial is required by method or preference

Typical Applications

• Adsorption‑prone or surface‑active analytes

• Low‑volume and low‑abundance samples

• LC‑MS and UHPLC autosampling

• Methods specifying deactivated or silanized glass

• High‑precision analytical workflows
