The ZetaReader® is a compact and easy-to-use, rapid zeta potential (ZP) analyzer that uses a sophisticated electrophoresis cell and high-resolution digital camera for real-time measurements.
Unlike most other ZP analyzers, the ZetaReader can make the measurement on a remarkably wide range of particle sizes, from 20nm to over 500microns. It is also available with a one- or three-channel titrator for studying changes in ZP as a function of pH or salt concentration for example. Samples are introduced directly from sample jars and bottles without the need for manual filling of cuvettes. The direct imaging technique used allows zeta potentials of both individual particles and flocs to be measured in the same suspension, plus optional image analysis. The measurements are effected without beam splitters, light intensity attenuators or compensation optics.
