Silica particles (SiO2-R) in the size range 100 nm – 100 µm

Monodisperse silica particles can be used in a variety of applications like medical diagnostics, for pharmaceutical and biotechnological purposes, in analytics, molecular biology, and others. Utilizing modified sol-gel strategies, microParticles GmbH has been developed high-quality silica particles in the nanometer and micrometer size range. The particles combine many favorable properties, such as high monodispersity (CV < 5 %), spherical shape, high optical transparency, high mechanical and thermal stability, or hydrophilic surface properties. They are non-porous and have a high density                   (1,85 g/cm³). Our monodisperse silica particles are available in more than 70 discrete sizes with particle diameters from     100 nm to 100 µm. Diameters and size distributions are measured by differnt measuring techniques like scanning electron microscopy, Differential Sedimentation (CPS disc centrifuge), Coulter-devices, and optical microscopy.
Silica particles from 100 nm - 29 µm are supplied as 5 % (w/v) aqueous suspensions, silica particles from 30 µm - 100 µm are supplied as 2,5 % (w/v) aqueous suspension.
