Cell counting

Achieve multiparameter quality control of your cell cultures using the CASY cell counter and analyzer. Based on the non-invasive Electrical Current Exclusion (ECE) principle, the CASY System allows fast, high-precision quantification of cell concentration, viability and more.

CASY-Technology, combines  a  proven  particle  measurement  technique,  referred  to  as  the  Resistance Measurement Principle, with a modern method of signal evaluation, pulse area analysis. Measurement  is  performed  by  suspending  the  cells  in an  electrolyte  developed  specifically  for  cell  counting. Since the cell viability is determined by electric current exclusion, viability dyes such as Trypan blue and Propidium iodide are not needed. Hence, cell viability determination need no longer be a terminal experiment.  

This advantage permits subsequent tests using the cells such as viability after a further time interval. The given result will be very accurate because not only are all steps performed robotically, but are high throughput (e.g. a million events/second). As there are more than 500 000 channels for a cell counting, once a cell is pass through the measuring pore, there would be a lot of channel monitoring for 1 cell.
