Beckman Coulter Vials Vi-Cell XR 4 ml Total of 1920 Vials

Beckman Coulter 723908 Vi-CELL XR Sample Vials (4 ml)

The Beckman Coulter 723908 is a specialized sample vial designed for use with the Vi-CELL XR Automated Cell Viability Analyzer. These 4 ml vials are precision-molded from high-purity polystyrene to ensure compatibility with the instrument's carousel and vacuum-driven autosampler. Engineered to facilitate the automated trypan blue exclusion protocol, these vials allow for the accurate aspiration of cell suspensions, ensuring consistent sample-to-reagent mixing ratios. Their standardized geometry is critical for maintaining the high-throughput performance and reproducibility of cell concentration, viability, and morphology measurements.

Technical Performance and Design

• Standardized Autosampler Fit: Specifically contoured to sit securely in the Vi-CELL XR 12-position carousel, ensuring precise vertical alignment for the instrument's sampling probe.

• Optimized Aspiration Geometry: The internal base design minimizes dead volume, allowing the analyzer to process samples efficiently even when working with limited volumes (0.5 ml to 2.0 ml).

• High-Purity Polystyrene: Manufactured from medical-grade, non-leaching plastic to ensure that the chemical integrity of the cell culture media and reagents is maintained during the analysis cycle.

• Clear Visual Monitoring: The transparent construction allows lab technicians to visually verify sample volume and uniformity prior to loading the instrument queue.

Key Benefits & Applications

• Automated Cell Counting: The primary consumable for assessing mammalian, insect, and yeast cell lines in biopharmaceutical and academic research.

• Bioprocess Monitoring: Essential for daily viability checks in bioreactor runs where consistent sampling hardware is required for data integrity.

• Seamless Workflow: The disposable "cup" format eliminates the need for wash steps between samples on the carousel, preventing cross-contamination and increasing lab throughput.

• Reliable Fluidics: Designed to prevent the formation of air bubbles during the probe's aspiration stroke, which is critical for accurate image capture in the Vi-CELL flow cell.
