PSi-G5.0 | Silica microparticles, no surface modification, green fluorescence, 5 um diameter


These 5 µm diameter green fluorescent silica particles have broad application for ligand separation. They are stable in aqueous buffers and organic solvents and are easy to isolate or re-suspend.

More Information

Many of our silica particles can also be provided in powdered form. Please contact Advance Scientific to see if this product is available as a powder or to request a quotation for bulk quantities of this product in either format.

Silica microparticles up to 1.5 µm in diameter are monodisperse and non-porous. Microparticles larger than 1.5 µm are porous and have a wider size distribution.

The image associated with this microparticle is used for illustrative purposes only and is not representative of the physical characteristics of these silica microparticles.
