Analyzer for measuring particle size and zeta potential

The Zetasizer Ultra is a versatile instrument for the characterization of particles in dispersion. From dynamic light scattering we are able to determine the size of particles from 0,3nm to 10µm.

Static light scattering in 90° or 173° angle is used for calculating molecular weight.

The electrostatic stability of the system can be characterized by the zeta potential. This is measured on principle of electrophoretic light scattering in special cuvettes.

Since our model of zetasizer is the most advanced one, it is possible to measure the concentration of particles by MADLS technique.
