Z2 COULTER COUNTER - Particle and Cell Size and Count Determination

Z™ Series COULTER COUNTER® Cell and Particle Counter uses the Coulter Principle (Electrical Sensing Zone Method) for sizing and counting particles.

The Z2 COULTER COUNTER is the latest addition to the Z™ Series COULTER COUNTER. In addition to reporting both count and concentration results, the Z2 adds the ability to provide size distribution of the cell population. The Z2, like the Z1™, uses the Coulter Principle (Electrical Sensing Zone Method) of counting and sizing of cells.

This technique provides accuracy, speed, versatility and reproducibility. The Z2 displays the entire size distribution graph, or the size statistics and counts between user selectable areas of the graph. 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.

Additional Benefit, Averaging Data

The Z2 COULTER COUNTER has the ability to average counts and channelyzed data from a series of up to 10 consecutive analyses. The more cells counted and sized the greater 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 COULTER COUNTER. Features of the AccuComp software include: size distribution statistics, data archiving, size trend analysis, result overlays, averages, graphs and tables, customizable reports, data import/export capability.
