Silica particles

Creative Diagnostics offers a comprehensive list of basic, coated, functional and conjugated silica particles with uniform size and shapes. Our silica particles in the size range of 10 nm to 1.5 µm are monodisperse and nonporous particles with a density of 2.0 g/cm³, while particles between 3 and 20 µm are porous particles with a density of 1.8 g/cm³.
