Instrument: Malvern Zetasizer Pro
Manufacturer: Malvern Panalytical
General Description: The Malvern Zetasizer Pro characterizes particle size, zeta potential, and molecular weight in dispersed systems using light scattering techniques. Dynamic light scattering measures Brownian motion to determine particle size distributions across sub-nanometer to micrometer ranges. Electrophoretic light scattering quantifies surface charge through particle mobility under applied electric fields. Non-invasive backscatter optics accommodate varying sample concentrations. The system features adaptive correlation algorithms and automated measurement optimization. Optional multi-angle detection provides enhanced size resolution. Temperature control enables studies of stability and aggregation behavior. The instrument supports measurements in various sample vessels including low-volume disposable cells. Automated titration accessories allow systematic investigation of size and charge changes with solution chemistry variations. Applications include colloid characterization, protein aggregation studies, nanoparticle formulation, emulsion stability assessment, and quality control across pharmaceuticals, nanotechnology, and materials science.
