SeraSil-Mag™ beads are compatible with chaotropic salt chemistry and vortex mixing, roller mixing and sonication.

Tightly controlled production processes result in core-shell beads which are uniform and spherical. The silica shell provides a high content of silanol surface groups and encloses the magnetic core. The submicron size allows for a high surface area and abundant binding sites. The narrow particle size distribution assures uniformity and consistency of the beads.

The magnetic nanoparticles within the core provide superparamagnetic properties to the SeraSil-Mag beads, resulting in extremely fast magnetic separation in the presence of a magnet. There is no residual magnetization when the magnetic field is removed, which further contributes to ease of handling during use.
