The Beckman Multisizer 3 Particle Counter is the top particle counter on today’s market.  The easy-to-use system accurately measures particle size, particle counts under the highest resolution and capable of counting/sizing at concentrated levels.  This ground breaking technology uses a method called Electrical Sensing Zone which measures volume, overall count, and surface area size distribution all in one run.  The Beckman Multisizer 3 Particlel Countermeasures particle sizes from 0.4µm to 1,200µm and unaffected by refractive index, color, shape, or composition.  The system uses a digital pulse processor which allows it to measure in real-time, increasing lab productivity.  The Beckman Multisizer 3 Particle Counterworks with organic electrolytes along aqueous samples and is mercury free making the particle counter environmentally friendly.  The Beckman Multisizer 3 Particle Countercomes with an improved design using a new style of aperture which is easy to swap out for selected desired size ranges. 

The instrument handshakes with a computer running Multisizer 3 software and can analyze cell cycle, cell growth, cell viability, pathogenesis, osmotic stress and phagocytosis.  The Particle Analyzer is ISO certified and is 21 CFR part 11 compliant, with a built in V-Check which allows for instrument validation such as IQ, OQ, PQ.  This unique feature allows the Multisizer 3 Particle Counterto meet such standards as cGMP and is regulated by the Food and Drug Administration (FDA).  The Beckman Multisizer 3 Particle Counter is also capable of detecting cell size and volume changes as they happen in real time making the system a must have for biologists. 

In addition, the system can determine Bacterial Aggregation in a culture using its multi-tube overlap feature.  Moreover, the Beckman Multisizer 3 Particle Counter can determine particle size and distribution.  If fine particles are the main population and not Gaussian size distribution, typically they’re not shown.  However, with the Multisizer 3 Particle Counter from Beckman Coulter, the instrument is able to determine volume percentage and number percentage size distributions, allowing the users to determine if the presence of these fine particles will affect their product.  System includes a 100µm aperture but can easily be swapped out by an additional aperture.  Contact us today to learn more about our Beckman Multisizer 3 Particle Counter.
