Zetasizer

A Zetasizer is a scientific instrument used to measure the size, shape, and surface properties of tiny particles or molecules in a liquid. It works by shining a laser light through a sample and analyzing how the light scatters or moves due to the particles’ behavior. This technique, called dynamic light scattering, helps researchers understand particle stability, distribution, and interactions. Zetasizers are widely used in pharmaceuticals, food science, and materials research to ensure consistency, quality, and performance of products involving small particles or molecules.
