Monodispersed Silica Microsphere

Characteristic

This series of silica microspheres are non-porous spherical particles with large specific surface area; hydrophilic surface and good dispersibility.

Application

because of its good optical and mechanical properties, it can meet the scientific research needs of the application field of inorganic particles. Silica microspheres are divided into two categories, the surface is unmodified (silicon hydroxyl group) and the surface is modified with functional groups such as carboxyl, amino and streptavidin, which can be widely used in nucleic acid separation, cell separation, immunoassay and other research field.

Storage  

Store at 2 – 8°C, do not freeze.
