Cell Counting

Both Z1 Single and Dual Threshold Models use the Coulter Principle (Electrical Sensing Zone Method) for counting cells or particles in the 1-120 micron size range. This technique provides accuracy, speed, versatility, and excellent precision; it is the accepted reference method for cell counting. Standard apertures are available in five sizes. In addition, for vey small sample volumes, ampoule insertable apertures may be used.

The Z1 Single Threshold Model

The Z1 Single Threshold instrument allows the operator to set one size threshold. Cells equal to or larger than this setting will be counted. Ideal as a fully automated instrument for the rapid enumeration of both tissue culture and blood cells from most any species. Excellent for rapid total cell count on cell lines containing cells of relatively uniform size.

The Z1 Dual Threshold Model

The Z1 Dual Threshold Model counts cells or particles in three regions, equal to or above the operator selected lower size, above the upper size setting and between the two sizes. Excellent when cell numbers between a selected size range are required. Instrument of choice when working with numerous cell types, containing variable cell sizes, or platelets.

Size Distribution Capability
