Remember, GMI employes manufacturer trained engineers and removes 100% of the risk in buying used particle counters from Beckman. GMI is the number 1 seller of refurbished:īeckmann Multisizer 4 Particle Counters in the US.

Using the Coulter Principle, a leading technology in high resolution and accuracy, the COULTER COUNTER Analyzers provide size distribution in number, volume and surface area in one measurement, with an overall sizing range of 0.4 µm to 1600 µm. This counter is excellent for determining a cell number between selected size ranges.Ĭall us today for pricing on the Beckman Coulter Z1 Dual Cell Particle Counter! COULTER COUNTER Analyzers are the most accurate particle sizing and counting analyzers. A unique oil displacement pump is used instead to obtain effective results.īeckman Z1 counters compute for cells and particles in three regions which are equal to or above the lower size selected by the operator, above the upper size setting and between these two sizes. These particle counters can produce pressure measurements with a high degree of accuracy and precision without the use traditional mercury manometers. This common calibration problem of other instruments is caused by changes in electrolyte conductivity and temperature. The Z1 is fitted with distinct features that heighten productivity, including the ability to eliminate calibration drift. Instrument calibration only requires a few steps to prompt automatic computation and arrangement of optimum instrument settings. Straight-forward messages are also displayed on the LCD screen to direct users in configuring set-up and analyses functions.

Having a dedicated START button, this device can complete a count and produce accurate results within seconds. The Beckman Coulter Z1 Dual Cell Particle Counter offers simple and direct operation, allowing users ease of use.

Powered Air-Purifying Respirator (PAPR) Units.

The more cells counted and sized the greater the statistical confidence in the result and the smoother the shape of the averaged size distribution. Additional Benefit, Averaging Data The Z2 has the ability to average counts and channelized data from a series of up to 10 consecutive analyses. 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. The Z2 displays the entire size distribution graph, or the size statistics and counts between user selectable areas of the graph. This technique provides accuracy, speed, versatility and reproducibility. The Z2, like the Z1, uses the Coulter Principle (Electrical Sensing Zone Method) of counting and sizing of cells.

In addition to reporting both count and concentration results, the Z2 adds the ability to provide size distribution of the cell population. The Z2 COULTER COUNTER is the latest addition to the Z Series COULTER COUNTER.
