Product Overview
Si3UM-10 Silica Microspheres are precision-engineered monodisperse silicon dioxide particles with a nominal diameter of 3 μm. Manufactured using advanced synthesis technology, they offer excellent particle size uniformity, low aggregation and outstanding suspension stability. Their highly spherical morphology ensures consistent performance across biological, analytical and industrial applications.
Supplied as a 2.5% aqueous suspension, Si3UM-10 features a naturally hydroxylated silica surface that can be further functionalized with amino, carboxyl, epoxy and other reactive groups. These microspheres are widely used for immunoassays, chromatography, biosensor development, calibration standards and surface chemistry research.
