Silica Microspheres

Product Introduction:
Silica microspheres are tiny particles, mainly composed of silicon dioxide (SiO₂), with high surface area and excellent chemical stability. They are typically spherical in shape, with a smooth surface and a uniform size distribution. In addition, they are chemically inert, non-toxic, and can be easily modified to enhance their performance for specific applications.

Our Products

Alfa Chemistry has the capability to manufacture silica microspheres on a large scale, ranging in size from 50 nanometers to 1000 micrometers. Our expertise also extends to surface modification to produce silica microspheres that are either non-functionalized or with specific functional groups such as carboxyl, amino, epoxy or streptavidin.

Today, silica microspheres have become increasingly important in applications such as nucleic acid isolation, cell separation, and immune or DNA-based analysis, owing to their unique properties and versatility. If you are interested in related products or have any specific requirements, please feel free to contact us.
