The Malvern Zetasizer Ultra is the most advanced tool for measuring size, charge, molecular weight and particle concentrations. The Multi-Angle Dynamic Ligh Scattering technique uses detectors at three different angles to provide accurate particle and molecular size distributions. It can measure sizes from 1 nm to 10 µm. Electrophoretic Light Scattering (ELS) measures the zeta potential of particles and molecules, through which the stability of a colloidal system can be assessed. It has precise temperature control and comes with an Autotitrator through which Zeta or Size vs pH titrations can be automated. With this instrument, you can study material stability, agglomeration, flocculation and isoelectric point.
