Particle Size Analyzer with Zeta Potential
Overview
Particle Size Analyzer with Zeta Potential
Korexan Co., Ltd. offers an advanced Particle Size Analyzer integrated with Zeta Potential measurement technology, designed for precise characterization of particles in liquid dispersions. Utilizing a combination of acoustic and electro-acoustic measurement techniques, the system enables simultaneous determination of particle size distribution and surface charge properties without the need for sample dilution. This ensures fast, accurate, and reliable analysis while preserving the original nature of even highly concentrated or opaque samples.
The instrument is suitable for a wide range of applications including nanoparticles, pharmaceuticals, emulsions, pigments, ceramics, and advanced material research. With its ability to measure multiple parameters such as zeta potential, pH, conductivity, and temperature in a single run, it provides comprehensive insight into dispersion stability and material behavior. The user-friendly software, automated analysis features, and robust design make it an ideal solution for research laboratories, quality control, and industrial process monitoring.
Key Features
