The Beckman Coulter Multisizer 4 Particle Size Analyzer provides realtime, multichannel analysis with user friendly control and 21 CFR part 11 compliance. This particle counter provides dynamic size measurements and counting in real time with an overall size range of 0.4 µm to 1600 µm through a digital pulse processing method in combination with the Electrical Sensing Zone. The Multisizer 4 draws the suspension with a mercury free isolated piston through the aperture at a metered steady rate for an accurate measure of concentrations or continuous flow for greater speed. Users also have the option to set their parameters for elapsed time or based on count. The Multisizer 4 allows users to choose the number of channels for an aperture from 4-400, low to improve appearance of a size distribution, or higher togive more detail about a particular size of particle.


The Beckman Coulter Multisizer 4 Cell Counter stores each pulse at maximum resolution, increasing Realtime resolution 100-fold, eliminating the need to re run just to see a particular size range. This particle counter can be 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.
