Instruments in the Zetasizer family are used to measure the particle size of dispersed systems from sub-nanometer to several micrometers in diameter, using the technique of Dynamic Light Scattering (DLS). Zetasizer systems are also used to analyze particle mobility and charge (Zeta potential) using the technique of Electrophoretic Light Scattering (ELS), and the molecular weight of particles in solution using Static Light Scattering (SLS).

The Zetasizer is available as the Zetasizer Advance range of laboratory benchtop systems (successor to the popular Nano range), and as the Zetasizer WT and AT Process systems.
