Xylem YSI 2950D-0 Benchtop Biochemistry Analyzer with ISE Module Upgrade

Xylem YSI 2950D-0 biochemistry analyzer configured with three modules: two biosensor modules and one ion-selective electrode (ISE) module. It supports biochemical and electrolyte testing for cell culture, fermentation, bioprocessing, clinical research, food and beverage quality control, and environmental analysis.

• Maximum chemistries: 6
• Analytes: 2 per module
• Sample size: 10–50 µL per module
• Enzyme response time: approximately 60 seconds for a single module; approximately 2–3 minutes for multi-module operation
• Precision: application-specific, typically CV <2%
• Linearity: ±5% of calibration value to maximum
• Inlet flow rate: 100–2,500 µL/min
• Supported sample formats: 96-well plates, 4-, 8-, and 24-position test tube holders, and microcentrifuge tubes
• Dimensions (W × D × H): 35.6 × 52.1 × 40 cm (14 × 20.5 × 15.75 in)
• Weight: 17.7 kg (39 lb)

The dual biosensor configuration supports simultaneous sample or analyte measurement, while the ISE module provides dedicated electrolyte analysis. Sensor-based detection, automated calibration, continuous-operation capability, and rapid response times support routine laboratory workflows and bioprocess monitoring.

Applications include:

• Glucose and lactate measurement in cell culture media
• Fermentation and bioprocess condition monitoring
• Electrolyte analysis using ion-selective electrodes
• Clinical and research biochemistry
• Food and beverage quality control
• Environmental and water testing
• Biotechnology, molecular biology, and biomanufacturing workflows
