Product Overview

Monodisperse silica microspheres are silica particles with highly uniform size and spherical shape. As a type of inorganic filler, they are widely used in electronic packaging, biomedicine, mechanical polishing, and liquid chromatography due to their large specific surface area, high chemical stability, excellent mechanical strength, and environmental friendliness.

Key Features

•High Sphericity: Perfectly spherical shape.

•Monodispersity: Strictly controlled particle size with a very small coefficient of variation.

•Stable Physical and Chemical Properties.

Applications

•Standard Calibration: Monodisperse silica microspheres are used as calibration standards for particle size analysis instruments (such as laser diffraction and electron microscopy).

•Chromatography Fillers: Widely used as stationary phases in High-Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC). Their uniform size and shape ensure high resolution and purity in separations.

•Biotechnology and Life Sciences: Functionalized silica microspheres can be used for immunoassay, cell separation, and drug delivery. Their uniform size ensures consistency and reproducibility.

•Catalyst Support: Can be functionalized as catalyst carriers, improving catalytic activity and selectivity.
