The Zetasizer Nano Z is a compact and specialised device for measuring the zeta potential in colloidal dispersions and nanoparticle systems. In contrast to the extended ZSP model, the Nano Z focuses primarily on analysing the surface charge of particles using electrophoretic light scattering (ELS). It is ideal for applications such as stability assessment of formulations or characterisation of biomolecules. The device is easy to use and provides reliable results for zeta-potential related questions. For further details please do not hesitate to contact us!
