EOSModel Classizer ONE -Advanced Particle Analysis Platform

SHARE
Classizer™ ONE represents a state-of-the-art particle analysis platform utilizing patented SPES and SPES² methods to perform multiparametric analysis, classification, and counting of particle mixtures. It is engineered for applications in research, custom particle formulations, dispersion formulation, and quality control across diverse sectors including life sciences, cosmetics, cosmeceuticals, pigments, inks, cements, abrasives, agrochemicals, and environmental sciences. The system quickly analyzes particle mixtures in both simple and heterogeneous liquids by dispersing or diluting a small sample aliquot in a filtered solvent, which is then passed through the device at a constant flow. Thanks to the patented SPES optical schemes, Classizer™ ONE provides detailed EOS CLOUDS data of the sample within minutes. Its robust design features custom electronics and industrial-grade components ensuring durability, reliability, and precision. It covers a dynamic range of 0.1 – 20 μm and a concentration range of 1E4-1E7 particles/mL, and it operates with laminar constant flows from 0.2 to 4 mL/min, managing viscosities up to 10cS. The device includes chemically-compatible materials such as Quartz, BK7, PTFE, PCTFE, FEP, FFKM, PEEK, and Stainless Steel for wetted surfaces and couplings. Moreover, tailored hardware solutions can be developed based on specific user requirements. The Classizer™ ONE can be paired with standard syringe pumps or high-quality peristaltic pumps for regular R&D activities and can integrate with EOS's automatic sample managers and autosamplers to enhance measurement throughput and reliability in formulation and quality control processes. Technical specifics vary by model, configuration, and sample preparation.
