Cospheric develops, manufactures and distributes precision spherical particles. We ship worldwide daily enabling scientists and engineers to make breakthroughs in their respective fields. We partner with innovators in many industries to create additional value and competitive advantage for their products and areas of research. Our current focus is developing, manufacturing, and distributing precise microspheres - engineered particles in a variety of colors, materials, densities, fluorescent, phosphorescent, conductive, neutrally-buoyant and paramagnetic properties. We offer solid, hollow, coated, monodisperse, spacer grade, and density marker beads. Solid and hollow glass, silica, PMMA, polyethylene, polystyrene, polypropylene, silver-coated glass, aluminum-coated retroreflective particles, TiO2-coated spheres and more unique beads in diameters from below 1micron to 15mm. We specialize in manufacturing custom spheres with specific density between 0.95g/cc and 1.3g/cc, particles with exceptional sphericity and tight size distribution, as well as spheres for PIV and flow visualization studies.
