The Beckman Coulter Multisizer 4 particle counter is a reliable accurate realtime, multichannel analyzer with high reproducibility. Being 21 CFR part 11 compliant makes this particle counter a valuable asset for both research and development, as well as quality control in either an industrial or life science environment. The Beckman Coulter Multisizer 4 particle counter uses a unique digital pulse processing method in combination with the Electrical Sensing Zone, that provides dynamic size measurements and counting in real time with an overall size range of 0.4 µm to 1600 µm. Using a mercury free “Isolated pistion” the Beckman Coulter Multisizer 4 draws the suspension through the aperture either metered, or continuous flow, depending on needs, with options to allow users defined parameters based on particle count or elapsed time. Measurements are also multifactorial, providing information like number, volume, surface area size distributions and mass all in one measurement. Increased resolution and high speed digitalization gives you a more accurate characterization, with the use of various pulse parameters.


The Beckman Coulter Multisizer 4 particle counter is user friendly, controlled with an external PC using windows based software with wizards to help guide beginning users and drop down dialogue boxes giving access to all settings for more experienced users.  Statistical parameters as well as size and pulse data are automatically calculated by the Multisizer software, presenting a customized report of the results in numerous formats. Data may be stored for supplementary analysis or reporting at a later time, eliminating the need to run the sample again.  The EZAccess reagent management system helps to administrate reagents and waste.
