Polystyrene (PS) Microspheres

Product Introduction:
Polystyrene (PS) microspheres are spherical particles made from polystyrene, a synthetic aromatic hydrocarbon polymer. These microspheres are available in a variety of sizes and can be manufactured with precise size control. They are widely used in scientific research due to their uniform size, smooth surface, and customizable properties, including functionalization with various chemical groups.
