BORUISTAL high-purity monodisperse spherical silica microspheres are synthetic porous silica powders mainly composed of hydrated silica (SiO₂·nH₂O). As the mainstream silica-based packing media for chromatographic analytical columns, they feature high mechanical strength, excellent chemical stability and low solvent swelling.
Featuring narrow particle size distribution, customizable surface chemistry and uniform pore structures, our silica microspheres provide excellent mass transfer. Consistent physical properties reduce column backpressure, improve separation efficiency and column stability, and extend packing service life. They yield high-purity target compounds with great separation performance and cost efficiency, acting as core separation & purification media for pharmaceutical, biotech and fine chemical industries.
