The Zetasizer instruments provide the ability to measure particle size and zeta potential of particles or molecules in a liquid medium. The Zetasizer features unique technology for measurement over a wide concentration range, and precise temperature control to give reproducible, repeatable and accurate measurements. Other key parameters like conductivity and particle concentration can also be measured. The Zetasizer range has been designed so that a minimal amount of user interaction is necessary to achieve precise and repeatable results.


Measuring range for size: 0.3 nm - 10 μm (diameter) ² Zeta potential Measurement principle: Mixed-mode measurement, phase analysis light scattering (M3-PALS) Size range: 3.8 nm – 100 μm (diameter) ² Minimum sample volume: 20 μL ⁶ Concentration range: 1 mg/mL ³ - 40% w/v ⁴ ⁵ Sample conductivity range: Maximum: 260 mS/cm Accuracy: ± 10%
