Affimag Magnetic SiO2 Microsphere

The magnetic silica particles are particularly useful in applications of DNA/RNA purification. We offer two types of magnetic silica: Affimag SLE and SLC with the former prepared by embeding the magnetic nanoparticles in the silica matrix and the later by coating the silica core with a layer of magnetic particles.
