Beckman Multisizer 3  Particle Size Counter  with Software Fully Refurbished.90 Day Warranty Description – The Beckman Coulter Multisizer 3 is a very robust particle size analyzer that studies a wide range of materials. This instrument provides volume and size distributions in number, volume, surface area and mass, with an overall range of 0.4µm – 1200µm. The Multisizer 3 uses the Electrical Sensing Zone Method to measure particle volume, a direct measurement of a physical property of the particle. High-speed digitalization of the signal allows the use of pulse area analysis and other techniques for additional particle characterization. The data can be analyzed and formatted in numerous ways, or stored and reanalyzed at a later date with no need to analyze the sample again.
