The Beckman Coulter Z2 is the latest cell and particle counter of the Z Series. Following the Z1, this model also makes use of the Coulter Principle known as the Electrical Sensing Zone Method for counting and sizing cells. Accuracy, speed, versatility and reproducibility is expected in the application of this technique.

In addition to reporting both count and concentration results, the Beckman Z2 can provide size distribution of the cell population as well. This particle counter also has the ability to display various data between user selectable areas of the graph including the entire size distribution graph as well as the size statistics and counts. Moreover, the cursor positioned on the graph aids in determining the cumulative count and the cumulative number percent above and below a size.

The Beckman Coulter Z2 Cell and Particle Counter can average counts and channelized data from a series of up to 10 consecutive analyses. Greater statistical confidence in the result as well as a smoother shape of the averaged size distribution can be obtained as the number of cells counted and sized is increased.
