Bioprocessing requires tight control of key nutrients and byproducts to optimize growth of cells in culture and maximize the yield of products. YSI analyzers and monitors provide fast, accurate measurements of single or multiple parameters in benchtop or on-line applications. YSI 2900 Series Analyzers are a popular industry choice for measuring analytes such as glucose, glutamine, glutamate, lactate and many more. The YSI 2900 incorporates two enzyme electrode biosensors. The YSI 2950 utilizes the same proven technology as the YSI 2900, and offers up to six electrodes for measurement of analytes plus ammonium.
