Microsphere market is fragmented and highly diverse in order to serve numerous widely varying applications that microspheres are used for, ranging from bond line spacers in electronics, to drug delivery vehicles in pharmacology, to contamination studies in chemical process troubleshooting, to microscopy size standards in applied physics, to modeling fluid flow in airspace and distribution of particles in agriculture. The list of precise high-quality microspheres with specific properties designed for unique applications is endless and getting longer every day as new requirements are being defined by our customers. For this reason Cospheric currently offers over 1500 unique microspherical, nanospherical and spherical products with different properties and always has more products coming through the pipeline. For those applications were NIST-traceability is important, Cospheric offers NIST-traceable Microspheres Certificate of Analysis, which can be purchased for any product.

We offer conductive, paramagnetic, fluorescent, phosphorescent, photocatalytic, neutrally-buoyant, monodisperse spacer spheres (particle size standards), density marker beads, custom density, custom coatings and many other properties of microspheres. If you don't see the microspheres with the exact properties you are looking for, please contact a microparticles expert for a recommendation or a custom quote.

CATEGORIES
Electrically conductive microspheres are often used as a conductive filler that is lighter than solid metal in paints, adhesives and composites to provide electrical conductivity.
Density marker beads are small colored microspheres of known mass density that are used for calibrating density gradients and determining density in gradient columns.
Brightly colored and fluorescent microspheres are designed for use as precision flow tracers and seed particles for water flow visualization and particle image velocimetry (PIV).
Fluorescent polyethylene microspheres in nine unique formulations emit bright colors at various wavelength and become highly visible when illuminated by UV light. Highly valuable in process diagnostics and troubleshooting, process flow, medical research and other industries.
Monodisperse particles are often used as as calibration standards and tracer particles for qualifying medical devices and in many biotechnology applications.
Paramagnetic microspheres have the ability to increase in magnetization with an applied magnetic field and loose their magnetism when the field is removed.
Phosphorescent particles are used for process study and blind tests especially in medical technology industry, diagnostics, troubleshooting, process flow, medical research and other industries. Particles exhibit a strong long-afterglow phosphorescent response and are stable in solution.
Photospheres provide a hydrophyllic, buoyant, filterable and reusable alternative to solid titanium dioxide nanoparticles for photocatalytic water treatment. Their buoyancy also enables application in open water systems, where solar UV wavelengths stimulate the photocatalytic activity.
Retroreflective Microspheres are made by applying a half-shell aluminum coating on solid barium titanate glass microspheres. The spheres hemispherically coated with a thin aluminum shell produce a bright retroreflective response directed back to the light source.
Currently half-shell or hemispherical coatings can be applied to any sphere (glass, polymer, ceramic) in sizes 45micron in diameter and higher. Each coating is custom formulated for color, charge, magnetic, electric, and surface properties, and solvent resistance per customers’ needs.
