Product Overview
Si5UM-10 Silica Microspheres are precision-engineered monodisperse silicon dioxide particles with a nominal diameter of 5 μm. Manufactured under strict quality control, they exhibit excellent particle size uniformity, low aggregation and superior suspension stability. Their highly spherical morphology ensures reliable performance in analytical, biological and industrial applications.
Supplied as a 2.5% aqueous suspension, Si5UM-10 possesses a naturally hydroxylated silica surface that can be further functionalized with amino, carboxyl, epoxy or other reactive groups. These microspheres are widely used in immunoassays, chromatography, calibration standards, biosensors and surface chemistry research.
