Sciex Beckman Sample Vial Tray for Sciex PA 800 Plus or P/ACE MDQ Plus - 3 Trays

SCIEX Beckman Coulter 48-Well Sample Vial Tray – For Universal 1.8 mL Vials and Microvials, High-Throughput Autosampler Architecture, Capillary Electrophoresis Replacement Accessory (MPN: A94461)

The SCIEX Beckman Coulter A94461 (also cataloged as A94461 / A94461-EA) is a precision-engineered chromatography autosampler consumable tray designed explicitly to provide stable, organized sample positioning inside high-performance capillary electrophoresis (CE) systems. Injection-molded from a high-durability, chemical-resistant polymer matrix, this 48-well sample vial holder features an exact 6 x 8 grid layout calibrated to accommodate standard 1.8 mL universal vials, microvials, and specialized PCR vial holders. Engineered to withstand the dynamic temperature shifts of the instrument's internal sample cooling compartment (4 C to 60 C), this replacement tray drops seamlessly onto the parallel track auto-sampler tracks of the SCIEX PA 800 Plus, CESI 8000 Plus, and P/ACE MDQ Plus lines. Its strict mechanical geometric tolerances ensure perfect alignment with automated system electrodes and vial cap openers, maintaining a leak-safe pressure seal for accurate and reproducible sample injection volumes.

Technical Performance and Structural Design

• Uncompromising Auto-Sampler Alignment: Molded to absolute geometric dimensions ensuring the tray locks perfectly onto the internal inlet or outlet sample tracking lanes. This precision blocks alignment drift, allowing the system's mechanical arm and electrodes to enter vials cleanly without causing needle deflections or system errors.

• Comprehensive Vial Multi-Format Utility: The 48-place structural wells securely support standard 1.8 mL universal vials, 200 µL microvials, and specialized NanoVials, allowing researchers to run volatile organic matrices, highly polar compounds, and micro-volume samples in a single sequence.

• Thermal Equilibrium Stability Matrix: Crafted from an advanced polymer blend optimized for rapid heat transfer and high structural stability. It matches the thermal performance of cooled sample bays, preserving fragile proteins, monoclonal antibodies (mAbs), and enzyme buffers down to 4 C.

• Permanent Grid-Coordinate Branding: Imprinted with high-contrast, alphanumeric row and column markings (A1 through H6 matrix). These clear indicators facilitate quick human visual checks during loading, reducing manual pipetting positioning errors before automation loops begin.
