YSI Life Sciences

Innovative Enzyme Biosensor Technology
Process Monitoring & Control
Simple, Versatile Food Analysis


YSI Life Sciences products provide measurement solutions for clinical, industrial, and research applications. YSI pioneered enzyme electrode technology for whole blood glucose measurements and further developed that technology for many clinical and industrial applications.


Bioprocessing and Online Monitoring & Control
YSI analyzers measure important nutrients and metabolites including glucose, lactate, glutamine, glutamate, ammonium, potassium, ethanol, methanol and more.

YSI offers several products for on-line monitoring and control of key analytes in cell culture and fermentation. Check out our online monitor and control solutions here.


Biofuels & Renewable Energy
YSI analyzers measure xylose, glucose, ethanol and more for process monitoring in cellulosic biofuel research and production.



Food & Beverage
YSI analyzers measure selected key ingredients and byproducts in process settings and in quality assurance laboratories. Among the analytes are glucose, sucrose, lactose, starch, choline, glutamate and ethanol. In food spoilage applications lactate and ethanol levels provide quantitative evidence of unwanted microbes.


Medical Research
YSI analyzers measure glucose and lactate in blood, plasma, serum and cerebrospinal fluid. YSI 2900 Series Analyzers are used extensively for diabetes, cancer, and stem cell therapy research. Other applications include glucometer manufacturing settings and exercise physiology studies. Results provide information related to growth factors, metabolism, toxic agents, and more.
