Beckman Coulter Z2 Particle Counter

Beckman Coulter Z2 Particle Counter

Cambridge ID #: 12488

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 has the ability to average counts and channelized 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.
