The Beckman Multisizer 3 Particle Counter is an easy-to-use system that accurately measures particle size, particle counts under the highest resolution and capable of counting/sizing at concentrated levels.  This groundbreaking 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 Particle Counter measures 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 Counter works with organic electrolytes along with aqueous samples and is mercury-free making the particle counter environmentally friendly.  The Multisizer 3 comes with an improved design using a new style of the 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 Counter to 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 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.  The 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.
