At the most basic level, a particle is a discrete sub-portion of a substance. Particle characterization is the process of identifying various particles by shape, size, surface properties, charge properties, mechanical properties and microstructure.

Covering the entire spectrum of particle characterization needs, the Beckman Coulter instruments use techniques that include the Coulter principle, laser diffraction, light scattering and polarized intensity differential scattering (PIDS) to provide the data required for specific application(s).

Multisizer 4e Coulter Counter

A highly versatile particle counting and characterization system

The Multisizer 4e uses the Coulter principle to detect particles via electrical zone sensing, regardless of the particle’s nature or optical properties. This renders the Multisizer 4e an ideal tool for detecting and counting a wide variety of particles including Mammalian cells, bacteria, yeast, abrasives, toner particles, cell aggregates, spheroids and large protein aggregates.

Vi-CELL BLU Cell Viability Analyzer

Greater sample capacity

The Vi-CELL BLU automates the Trypan Blue Dye Exclusion method for cell viability analysis. The Vi-CELL BLU expedites processing with the option to use a 24-position sample carousel or a 96 well plate for sample delivery. Other enhancements incorporated in the Vi-CELL BLU include fully automated sample preparation; analysis and post-run cleaning; use of small sample size; fast sample processing time; small laboratory footprint; a user-friendly reagent system; cell viability reported in percentage, concentration, and cell count; large sample capacity; and data integrity tools.


Speed, reliability and low sample volume

Measuring samples as small as 65 µL and returning results in just 35 seconds, the new Vi-CELL MetaFLEX bioanalyte analyzer evaluates pH, pO2, pCO2, glucose, lactate, electrolytes and more. With less maintenance, more reliability and a surprisingly small footprint, it’s a sophisticated research solution that profiles test samples quickly, easily and accurately - keeping test cell cultures in balance, viable and growing.

DelsaMax Series

Speed, reliability and precision

The DelsaMax Series of light scatter analyzers offer incredible speed, reliability, and precision for particle and nanoparticle characterization. Each instrument allows the investigator to gain valuable insight into the samples through non-destructive testing of even the smallest quantities of materials. The DelsaMax Series feature dynamic and static light scattering detection; rapid, non-destructive Zeta Potential analysis; minimal use of sample volume (as little as 1 μL needed for size analysis); and intuitive, easy-to-use software.
