Product Overview
Si30UM-10 Silica Microspheres are precision-engineered monodisperse silicon dioxide particles with a nominal diameter of 30 μm. Produced using advanced synthesis technology, these microspheres provide excellent particle size uniformity, high purity, low aggregation and outstanding suspension stability. Their highly spherical morphology ensures consistent and reproducible performance across analytical, biological and industrial applications.
Supplied as a 2.5% aqueous suspension, Si30UM-10 features a naturally hydroxylated silica surface that can be readily functionalized with amino, carboxyl, epoxy or other reactive groups. These microspheres are widely used in immunoassays, chromatography, calibration standards, biosensor development, cell separation research and advanced surface chemistry applications.
