Cytiva Xuri W25 Cell Expansion CBCU Unit for Precise Bioreactor Gas and pH Control

The Cytiva Xuri W25 Cell Expansion CBCU Unit is a specialized bioreactor control module designed to regulate critical culture parameters essential for cell expansion workflows in biotechnology and molecular diagnostics. This compact unit integrates precise gas flow and environmental controls for optimal cell culture conditions in bioprocessing applications.

• Gas flow range: 50 to 1000 mL/min with total flow accuracy of ±(10 + 3% of read value) mL/min
• Fast fill capability: Approximately 3 L/min for rapid gas adjustment
• CO2 control: Adjustable from 0% to 15% CO2 with ±0.4% control accuracy and ±0.5% measurement accuracy at 5% CO2, calibrated for air/N2 mixtures
• O2 control: Ranges from 0% to 50% O2 when mixed with N2, and 21% to 50% when mixed with air, with ±0.6% control accuracy and ±(0.6 + 1%) measurement accuracy
• pH control: Measurement range from pH 4.5 to 8.5, control range from pH 6.0 to 8.0, with measurement accuracy ±0.05 pH and control accuracy ±0.05 pH
• Dissolved oxygen (DO): Measurement range 0% to 250% air saturation, control range 0% to 100% air saturation, with measurement accuracy of ±5% (excluding atmospheric pressure variations)
• Compact dimensions: 276 x 117 x 360 mm (WxHxD), weight 4.8 kg, excluding software

This control unit is critical in biopharmaceutical production pipelines and widely adopted in synthetic biology research for maintaining stringent bioreactor environmental conditions. It supports live-cell imaging, cell culture optimization, and gene editing workflows by delivering precise control over gas composition, pH, and dissolved oxygen. The Xuri W25 CBCU unit enhances bioprocessing reproducibility and is a valuable component in modern cell expansion and molecular biology laboratories.
