Sciex Beckman Micro Vial Tray for Sciex PA 800 Plus or P/ACE MDQ Plus 4 Trays

SCIEX Beckman Coulter 48-Well Microvial Tray – For Automated Micro-Volume Sample Management, Capillary Electrophoresis Autosampler Accessory (MPN: 144444)

The SCIEX Beckman Coulter 144444 (also cataloged under laboratory distribution systems as 144444-EA or SKU 6828) is a precision-engineered chromatography autosampler tray designed specifically for handling micro-volume and ultra-low quantity samples within high-performance capillary electrophoresis (CE) networks. Injection-molded from a high-durability, chemically inert polymer matrix, this specialized 48-well container is specifically configured to fit smaller-diameter microvials and specialized PCR vial profiles. The tray features an exact 6 x 8 grid pattern that drops seamlessly onto the parallel track autosampler stages of the SCIEX PA 800 Plus, CESI 8000, and P/ACE MDQ Plus lines. Built to maintain strict dimensional stability within cooled internal sample compartments (4 C to 60 C), its precise design guarantees flawless mechanical alignment with automated system electrodes and sample needles, reducing the risk of expensive needle strikes during micro-volume injections.

Technical Performance and Platform Integration

• Microvial Geometric Optimization: Machined with specialized 48-well boring channels contoured to stabilize high-recovery microvials, keeping small, micro-volume liquid columns centered for the system injection needle.

• Flawless Mechanical Robotics Alignment: Molded to exact geometric dimensional tolerances that lock onto automated inlet and outlet sample tracks. This eliminates tray shifting, allowing automated electrodes and capillary columns to clear the well boundaries cleanly.

• Thermal Equilibrium Matrix Stability: Crafted from a high-performance polymer matrix engineered for uniform heat transfer. It responds quickly to cooled instrument chambers, protecting temperature-sensitive proteins, enzymes, and nucleic acids from degradation.

• Permanent Alphanumeric Coordinates: Imprinted with high-contrast row and column markings for clear identification. These clean indicators allow technicians to quickly cross-check positions, minimizing placement errors before automated sequences begin.
