Product Overview
Si1UM-10 Silica Microspheres are precision-engineered monodisperse silicon dioxide particles with a nominal diameter of 1 μm. Manufactured using advanced synthesis technology, they exhibit excellent particle size uniformity, low aggregation and outstanding dispersion stability. Their uniform spherical morphology makes them suitable for both research and industrial applications requiring highly reproducible performance.
Supplied as a 2.5% aqueous suspension, Si1UM-10 features a naturally hydroxylated silica surface that can be readily functionalized with amino, carboxyl, epoxy or other reactive groups. These properties make the microspheres an excellent platform for immunoassays, chromatography, biosensors, calibration standards and surface modification studies.
