Modell: Zetasizer Nano ZS


Measurement of particle size, zeta potential and molecular weight of samples with little or no dilution possible. Usage of disposable folded capillary zeta potential cell


Particle size: NIBS (Non-invasive back scatter) technology enables measurements of particles from 0.6nm to 6 mm.

Zeta potential: M3-PALS (phase analysis light scattering) technology enables measurements of zeta potential in aqueous and non-aqueous dispersions.

Molecular weight: An avalanche-photodiode detector and fibre detection optics give the sensitivity and stability required for absolute molecular weight measurement.
