NIST-traceable microspheres manufactured out of glass, polyethylene, PMMA, cellulose acetate, stainless steel, silica, zirconium and other materials. Metal, fluoro, and silane coatings on solid and hollow glass microspheres. Monodisperse and polydisperse grades of microparticles.
-
Microspheres with specific properties, such as conductive, fluorescent, phosphorescent, paramagnetic, photocatalytic, retroreflective are offered in a variety of colors, sizes and densities. Density marker beads and janus particles. PIV tracer particles and bond line spacers.
-
Microspheres in a rainbow of bright colors, uniform, consistent, highly spherical properties. The colorant is fully embedded into the microsphere. It will not fade over time or leach out into the solution. Custom color microspheres on request.
-
Metal-coated solid and hollow glass and polymer microspheres, including silver, gold, aluminum, nickel coatings. Other coatings such as fluorochemical, silane and TiO2 and ZnO. Custom coatings and partially coated spheres (janus particles) on request.

Microsphere density is a critical parameter when selecting microparticles for a specific application. Do the spheres need to be neutrally-buoyant in the fluid for flow visualization or PIV applications? Do they need to float or sink? Is a set of density marker beads needed for density gradients?
-
Diameter or particle size of microspheres, as well as particle size distribution, is a critical factor when selecting microspheres for a particular application. Microspheres with diameters from nanometers to millimeters are offered in a variety of grades from bulk options to highly monodisperse spacer grade spheres.
