Product Overview
Si13UM-10 Silica Microspheres are precision-engineered monodisperse silicon dioxide particles with a nominal diameter of 13 μm. Produced using advanced synthesis technology, these microspheres exhibit excellent particle size uniformity, low aggregation and superior suspension stability. Their highly spherical morphology delivers reliable and reproducible performance in analytical, biological and industrial applications.
Supplied as a 2.5% aqueous suspension, Si13UM-10 features a naturally hydroxylated silica surface that can be easily functionalized with amino, carboxyl, epoxy and other reactive groups. These properties make the microspheres suitable for immunoassays, chromatography, calibration standards, biosensor development and surface chemistry research.
