Met One Z Series COULTER COUNTER


Cell Counting:

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

The Z1 Single Threshold Model:

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

The Z1 Dual Threshold Model:

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

Size Distribution Capability:

The Z2 COULTER COUNTER is the latest addition to the COULTER COUNTER Z Series. In addition to concentration results and reporting both count the ability to provide size distribution of the cell population is added by the Z2, this like the the Z1 uses the Coulter Principle (Electrical Sensing Zone Method) of sizing of cells and counting. This technique provides speed, versatility, reproducibility and accuracy. The entire size distribution graph or the size statistics and counts between user selectable areas of the graph is displayed in the Z2. In addition, this instrument displays the cumulative count and the cumulative number % above and below a size determined by the cursor positioned on the graph.


Data Sheet

Met One Z Series COULTER COUNTER

Additional Benefit and Averaging Data:

The Z2 has the ability to average counts and channelize data from a series of consecutive analyses up to 10. Sized the greater and the more cells counted the statistical confidence in the result and the smoother the shape of the averaged size distribution.

PC Data Acquisition:

The Beckman Coulter Windows based AccuComp software package is available for quick and accurate calculation and presentation of sample data statistics from the Z2. The AccuComp software include features of customizable reports, size distribution statistics, graphs and tables, size trend analysis, averages data archiving, data import/export capability and result overlays.
