Beckman Coulter Vi-Cell XR Automated Cell Viability Counter for Tissue Culture and Bioprocessing

The Beckman Coulter Vi-Cell XR is an automated cell viability counter optimized for trypan blue exclusion cell counting, widely used in *tissue culture*, *bioprocess monitoring*, and *biopharmaceutical production*. This system provides consistent and reproducible measurements of cell viability, concentration, size, and morphology, reducing variability inherent in manual hemocytometer counts.

Key features include:

• 12-position autoloader allowing unattended analysis of up to 10 samples simultaneously
• Rapid sample processing with run times under 2.5 minutes per 0.5 mL sample
• Supports analysis of mammalian cells, CHO cells, yeast, and related suspension cell types commonly encountered in molecular diagnostics and bioprocessing workflows
• Automated mixing, staining, imaging, and image-based analysis improve data reliability and standardization for regulated laboratory environments
• Viability range from 0 to 100% and cell concentration range between 5 x 10^4 to 1 x 10^7 cells/mL ensuring broad dynamic range for diverse research and production needs
• Compliant with FDA 21 CFR Part 11 for secure data handling including user access control and audit trails, essential for clinical diagnostics and biomanufacturing quality control
• Compact footprint (16" x 20" x 18") and versatile operating temperature from 10°C to 40°C suit busy laboratory and upstream bioprocessing environments

This automated cell counter is critical for consistent viability trending, making it widely adopted in synthetic biology research, gene editing, and bioprocess development workflows. The Vi-Cell XR is a robust solution for researchers and laboratory professionals requiring precise, high-throughput cell counting and viability analysis in biotechnology, *live-cell assays*, and *production pipelines*.
