Complete Product Description

The Coulter Z1 Particle Counter uses the electrical sensing zone technique 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 very small sample volumes, ampoule insertable apertures may be used. 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 Coulter Z1 Particle Counter 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 Coulter Z1 Particle Counter eliminates calibration drift due to changes in electrolyte conductivity and temperature, a very common problem with other instruments.

Single Threshold Unit. This allows one to set one size threshold. Cells equal to or larger than this setting will be counted. Fully automated instrument for the rapid enumeration of both tissue culture and blood cells from most any species. Excellent for rapid total cell count on cell lines containing cells of relatively uniform size.

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