Beckman Coulter Multisizer™ 4 COULTER COUNTER®
The Higher Resolution for Particle Sizing and Counting
Discover the most versatile and accurate particle sizing and counting analyzer on the market. Using the Coulter Principle, also known as Electrical Sensing Zone (ESZ), the Multisizer 4 COULTER COUNTER provides size distribution in number, volume and surface area in one measurement, with an overall sizing range of 0.4 µm to 1600 µm. Its response is unaffected by particle color, shape, composition or refractive index. The Coulter Principle is the leading technology in high resolution and accuracy and it is enhanced even further in the Multisizer™ 4 by using a Digital Pulse Processor (DPP). DPP provides ultra-high resolution, multiple channel analysis and accuracy that is unattainable by other technologies. It all makes the Multisizer 4 indispensable for any research project involving sizing and/or counting. An equally powerful tool for quality control, the Multisizer 4 provides analysts with an easy-to-use system that is so technologically advanced, it can solve most particle sizing problems.
