Product Overview
SiS210NM-10 Standard Silica Microspheres are highly monodisperse silicon dioxide (SiO₂) microspheres with an average particle size of 210 nm. Manufactured using advanced synthesis technology, these microspheres provide excellent particle size uniformity, superior dispersion stability and minimal aggregation.
The naturally occurring hydroxyl (-OH) groups on the silica surface provide abundant reactive sites for chemical modification and biomolecule immobilization. These microspheres are widely used in diagnostics, chromatography, analytical standards, nanotechnology, functional coatings and biomedical research.
