Particle Size Analyzers / Coulter Counters

COULTER COUNTER Analyzers are the most accurate particle sizing and counting analyzers. 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. Its response is unaffected by particle color, shape, composition or refractive index .

The Coulter Principle is a versatile, robust, and accurate non-optical method for counting and sizing particles of all types. The technique uses electrical impedance to measure the volume of particles as they individually pass through an aperture of defined size.

Beckman Coulter has implemented the Coulter Principle in a wide variety of instruments from those designed for simple cell counting to large, automated clinical analyzers used for analysis of whole blood

DelsaMax Series Nanoparticle Analyzers

The fastest of its kind, the DelsaMax PRO allows simultaneous analysis of both particle size and zeta potential for sample volumes as small as 45 μl, in less than one second.

The DelsaMax CORE provides nanosizing of particles even at 1μL sample volumes—the lowest available today. And the DelsaMax ASSIST optimizes particle preparation by pressurizing the sample cell to reduce bubbling and interference. And across all models, DelsaMax software features an intuitive interface with fully customizable autocorrelation analysis and the ability to create robust distributions, overlays, custom user variables, reports and more.

LS 13 320 Particle Size Analyzer

The LS 13 320 Series is the most versatile and sophisticated laser diffraction particle size analyzer available today. Using the Fraunhofer and Mie theories of light scattering, the LS 13 320 Series offers the highest resolution, reproducibility and unsurpassed accuracy.

VI Cell Series Cell Viability Analyzers

The Beckman Coulter Vi-CELL automates the widely accepted trypan blue dye exclusion method for cell viability that has historically been performed manually with a light microscope and hemacytometer. In minutes, the Vi-CELL system measures 15 to 30 times the volume of the hemacytometer method with a more comprehensive number of parameters enhancing statistical reliability of the results

The Vi-CELL Series features the following key benefits:

Automated viability analysis using the trypan blue standard.


  • Rapid, reliable and objective results over manual he
  • Cell Imaging provides critical information not availab
  • Enhanced Image resolution provides cellular detail 10x
