Estapor® Fluorescent Microspheres

These photostable fluorescent microspheres have been specifically developed and patented by Estapor®. Made in polystyrene (PS) or in polyvinyltoluene (PVT), our fluorescent microspheres are monodisperse and uniform, ranging in size from 20 nm to 4 μm. Our fluorescent products are also available as plain or functionalized microspheres. To prevent dyes leaching and to provide the maximum of active surface, the fluorescent dyes are physically and irreversibly entrapped inside the microspheres.
