Colloidal Dynamics pioneered the multi-frequency Electroacoustic ESA Dynamic Mobility method for determining particle size and zeta potential in concentrated particulate dispersions and emulsions.
From optimizing the dispersion of nanoparticles to high-volume QC of semiconductor CMP polishing slurries, our instruments deliver direct measurements on your concentrated materials you can rely on.
Two purpose-built instruments backed by patented electroacoustic
technology and decades of field experience.
The easiest to use, most accurate zeta potential analyzer available. Measures a wide range of concentrated materials including CMP slurries, pigments, cements, minerals, ceramics, battery materials and emulsions up to 60% by volume – no dilution required. Features automated potentiometric and volumetric titrations including rapid, automatic determination of the particle Isoelectric Point.
Complete characterization of concentrated dispersions. Measures particle size, zeta potential, pH, conductivity and temperature in a single turnkey instrument.

AcoustoSizer update: Colloidal Dynamics has transferred the AcoustoSizer product line to Nippon Coke & Engineering. The companies are jointly developing the AcoustoSizer Grinding Monitor, which cuts particle-size and zeta-potential measurement from about three minutes to under 20 seconds for real-time grinding control. The ZetaProbe is unaffected.
