Xylem YSI 2950D-1 Modular Biochemistry Analyzer for Multi-Analyte Enzymatic Detection

The Xylem YSI 2950D-1 Biochemistry Analyzer is a precision modular biosensor system designed for rapid and accurate multi-parameter biochemical analysis. Featuring *two independent biosensor modules*, it can concurrently measure up to 4 chemistries with sample volumes ranging between *10 to 50 µL per module*. This analyzer is widely used in biotechnology, clinical diagnostics, and bioprocessing applications such as monitoring glucose, lactate, ethanol, glutamate, and other key metabolites.

Key technical specifications include:

• Analytes measured: glucose (0.05–25 g/L), lactate (0.05–2.70 g/L), glutamate (15–1460 mg/L), glutamine (30–1169 mg/L), glycerol, xylose, choline, hydrogen peroxide, sucrose, ethanol, methanol, lactose, galactose, and more.
• Enzyme response time: approximately 60 seconds per module for one analyte
• Precision: application-specific coefficient of variation typically below 2%
• Linearity: within ±5% from calibration value to maximum detection range
• Inlet flow rate: adjustable between 100–2500 µL/min
• Sample format compatibility: supports 96-well plates, 4-, 8-, and 24-place test tube racks, as well as microcentrifuge tubes
• Modular design: two biosensor modules allow flexible configuration for single or multi-analyte workflows, optimizing throughput for molecular diagnostics and synthetic biology workflows
• Consumables: buffer and waste bottle caps with tubing included; sensors and membrane probes are consumable and require replacement based on usage
• Automated sampling: integrates an auto-sampling system to enhance workflow efficiency and minimize manual handling, a feature critical in biomanufacturing and fermentation monitoring
