Cell Counters & Viability Analysis Systems

Cell counters and viability analysis systems are tools dedicated to counting and analyzing live and/or dead cells. Researchers working with cell cultures or primary cells will benefit from a robust cell counting solution, whether to determine cell concentration prior to cell passage or to assess cell viability following drug treatment. Automated cell counters, as compared to manual hemacytometers, can speed up this type of quantification, greatly improving throughput and productivity. These instruments can operate via electrical impedance ("Electrical Sensing Zone" method), direct imaging (either on a disposable slide or in a flow chamber), or flow cytometry. The most important variable to consider in selecting a cell counting solution is the ability to assess cell viability. Electrical impedance (the Coulter Counting approach) generally cannot distinguish live from dead cells (except by size); but imaging-based approaches can, by using trypan blue to stain dead (but not live) cells, just as in classic hemacytometry.
