YSI Life Sciences (UK)

Founded in 1948, YSI Life Sciences develops and manufactures scientific instruments, sensors and systems that serve a variety of scientific and industrial markets worldwide.

YSI has a long history in the life sciences and bioanalytical markets, most notably with the introduction of the world’s first commercial whole blood glucose analyser in 1975, which became the ‘Gold Standard’ in its field, with its highly accurate sensors and rapid results.

YSI’s ‘Gold Standard’ reputation has been earned due to its innovative biosensor technology. Using the inherent specificity of enzymes for a single target analyte, YSI’s proprietary immobilised enzyme electrodes allow a rapid, accurate and largely interference free measurement to be made.

Combining this trusted measurement technology with modern designs and features, YSI Life Sciences (UK) presents an impressive portfolio of biochemistry analysers, from the well established YSI 2300 Glucose/Lactate model, to its latest modular and innovative 2900 Series, which offers a range of configurations, options and accessories to meet laboratory needs, and capable of measuring up to 6 chemistries from Glucose, Lactate, Glutamine, Glutamate, Xylose, Ethanol, Methanol, Sucrose, Galactose, Lactose, Choline, Glycerol and Hydrogen Peroxide, plus ISE measurement of Ammonium and Potassium.

YSI became a member of the Xylem Group of Companies in 2011, and continues to be committed to providing its customers in the UK, and its overseas Distribution partners, with the best in scientific instruments, technical support, training and servicing through its UK offices in Fleet, Hampshire.
