Scharfe CASY Cell Counter

The cells suspended in CASYton, an electrolyte/buffer, are aspirated through a precision measuring capillary with a defined size. While passing through the measuring capillary, they are scanned with a frequency of 1 million measurements per second in a low voltage field between two platinum electrodes. The resulting electrical signals generated by a cell passing the measuring capillary are analyzed by amplitude, pulse width, course of time and resulting pulse area. The analyzed pulse areas of cell signals are cumulated and assigned in a calibrated multi-channel analyzer that has 512,000 differentiated size channels.       

Even the slightest changes in the cell are recorded absolutely, reliably and in a standardized way. Via changes in the cell membrane, even statements about the viability of the cells are possible.
