Beckman Coulter Z1 Coulter Coun

Listing description

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 Dual Threshold counts cells in three regions of the population, above the lower size, between the lower and upper thresholds, and above the upper size setting. This is the choice when more information on the cell population is desired, without additional analyses of the sample. The model is excellent for platelet applications and for use in those tissue culture laboratories working with a variety of cell types of different size.

Z1 instruments incorporate a unique, new oil displacement pump which delivers a high degree of accuracy and precision, and eliminates the need for mercury utilized in the traditional mercury manometers. The Z1 was specifically designed for simple operation. Enter the cell size (diameter or volume) and press START. The count is completed in seconds. Clear messages on the LCD display lead you through all set-up and analyses functions. Calibration requires only several keystrokes; optimum instrument settings are automatically computed and set. The constant current feature of the Z1 eliminates calibration drift due to changes in electrolyte conductivity and temperature, a very common problem with other instruments.
Product features:

* Mercury Free

With the Z1, data can be viewed in either count or concentration format. To obtain the concentration of the original sample, simply enter the dilution factor into the instrument and the original concentration will be automatically reported. The Z1 offers a choice of hard copy output from a complete analysis per run to a line by line presentation completely formatted to simplify later analyses comparisons.
