Product Overview
SiS40UM-10 Standard Silica Microspheres are highly monodisperse silicon dioxide (SiO₂) microspheres with an average particle size of 40 μm. Manufactured using advanced synthesis technology, these microspheres provide excellent particle size uniformity, outstanding suspension stability and minimal aggregation.
The naturally occurring hydroxyl (-OH) groups on the particle surface provide abundant reactive sites for chemical modification and biomolecule immobilization. These microspheres are widely used in chromatography, immunodiagnostics, analytical standards, cell separation research, functional coatings and advanced material development.
