Zetasizer Nano ZS90 Particle Size and Zeta Potential Analyzer

The Zetasizer Nano ZS90 particle size and zeta potential analyzer from Malvern Instruments combines static, dynamic and electrophoretic light scattering (SLS, DLS and ELS) techniques to measure a range of parameters for material characterisation in nanoparticles colloids and macromolecules including polymers ad protein solutions. Parameters include molecular weight (measured with SLS), particle / molecular size (measured with DLS), electrophoretic mobility and zeta potential (determined by laser doppler microelectrophoresis).

The zetasizer range features a range of models to support every budget and requirements. These include highly affordable solutions such as the ZS90 with 90 degree scattering technology and high-spec instruments such as the Zetasizer Nano ZSP, with non-invasive backscatter optics. The modular instruments can be supplied with a choice of accessories including the NanoSampler for precise, repeatable, automated sample loading and a range of cells and cuvettes for contaminant-free processing.
