Beckman Coulter Vi-Cell XR Cell Viability Analyzer, Beckman Coulter (CAT#: STEM-CA-0535-LGZ)

The manufacturer of Beckman Coulter Vi-Cell XR Cell Viability Analyzer is Beckman Coulter. Model is Vi-Cell XR. The new Vi-CELL series of cell viability analyzers provides an automated and cost-effective means to perform trypan blue dye exclusion. These data are critical to the decision-making process for basic tissue culture cell passaging and maintaining optimal culture conditions in bioreactors. Applications of cell and tissue culture in life science research, including recombinant protein and biopharmaceutical production, require the accuracy, precision and automation available only on the Vi-CELL Cell Viability Analyzer. Determination of cell viability was performed manually using a light microscope and a hemocytometer. This technique has significant drawbacks due to the subjective determination of cell counts, as well as manual, time-consuming steps. In contrast to manual techniques, Vi-CELL automatically performs video imaging of trypan blue and flow cytometry. Query results are in minutes.
