Zeta-Sizer
Zeta-Sizer
Modell: Zetasizer Nano ZS
Kurzbeschreibung
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
Beschreibung
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.
Accessories:
MPT-2 Autotitrator
Automated titration and sample preparation
measuring zeta potential as a function of pH, conductivity and other parameters
Operation is fully automated
