Welcome to YSI Life Sciences

YSI Life Sciences is a part of YSI Incoporated. Founded in 1948 and formerly known as Yellow Springs Instrument Company, YSI develops and manufactures scientific instruments, sensors and systems that serve a variety of scientific, environmental, and industrial markets worldwide.

YSI has a long history in the life sciences and bioanalytical markets, most notably with our introduction of the world’s first commercial whole blood glucose analyzer in 1975. Today our bioanalytical systems measure critical data over a wide range of applications —from diabetes research to bioethanol production.

YSI Life Sciences and its selling partners are committed to making your time more productive. We dedicate ourselves to that task in everything we do—from the way our products are designed to how our customers are served. Here are a few ways that we can help you be more effective.

Uniquely Dedicated
Being an employee-owned company gives us a distinct advantage. Everyone here has a financial stake in your success. It shows in how well we build our instruments (USA manufactured). And it's demonstrated in our unmatched level of commitment to your satisfaction.

Faster Results
We design instruments that are accurate and reliable, so you'll spend less time correcting and verifying your results. And every product has been designed to be easy to set up and use.

Less Maintenance
Better engineered instruments mean less time fixing and replacing them. We have equipment in labs around the world—maybe even yours—that still operate flawlessly after 10 years or more.

YSI bioanalytical instruments are trusted in critical bioprocess monitoring, clinical research and diagnostics, glucometer manufacturing, food and beverage processing, and most recently in biofuel production and research.
