The ZetaPlus uses electrophoretic light scattering to determine the zeta potential of colloidal-sized material suspended in water or polar solvents. Easy to Use: Simple cell design: one piece, easy fill and throwaway. Automatic: Single push-button operation: pre-aligned optics and no cell calibration. Small footprint: integral powerful 386/387 Compact: computer. Particle sizing by Dynamic Light Scattering is available as an option. Ideal for use in QC and R & D labs. The ZetaPlus has the best price/performance ratio of any zeta potential analyzer. For free technical literature
