Optical micrograph of 4.6 µm silica beads
microParticles GmbH has expanded its product line of dense silica research beads. With optimized Sol-Gel procedures particle diameters of up to 5 microns are achieved. The particles come as 5 wt.-% aqueous dispersions or in dry powder form. The main product characteristics are:
- Particle diameters above 1 micron up to 5 microns.
- Narrow size distribution (CV 6 - 7 %).
- Spherical particles with smooth surface.
- Surface functionalities (carboxyl, amino groups) available on request.
