The ZetaProbe is the easiest to use, most accurate zeta potential analyzer available. Samples can be measured without dilution or sample preparation at concentrations up to 60% volume. Even the direct measurements of pastes, gels, cements, and other difficult materials are possible with the ZetaProbe.

Traditional characterization techniques require sample dilution and sample preparation which are both time-consuming and error-prone. Our patented multi-frequency electroacoustic technology eliminates these problems. The ZetaProbe measures zeta potential directly, under true sample conditions, at concentrations as high as 60% volume.

The ZetaProbe features a compact design with built-in titration, versatile dip probe sensor, and software wizards. Automatic titration offers unattended rapid isoelectric point determination, as well as optimum dispersant or flocculant level control in a click of a button. The ZetaProbe offers many advances not found in other analyzers including automatic correction for particle size and double layer distortion. Yet, its easy to use software & rugged design makes the ZetaProbe ideal for use in research and plant optimization!
