By Color

Cospheric offers an exclusive product line of brightly-colored polyethylene microspheres. Cospheric's polyethylene micropheres range in size from 10micron to 1000micron (1 millimeter) and in some cases up to 1.2mm. The uniqueness of our product is that the colorant is bright, fully embedded into the microsphere, uniformly distributed, and will not fade over time or leach out of the particle into the solution. The colored microspheres are conveniently provided in a glass vial or a glass jar as a free-flowing dry powder, which does not have an expiration date and can be safely stored at room temperature indefinitely.

Currently we have a large stock of sizes in clear (uncolored polyethylene), white, red, blue, green, black (paramagnetic), yellow, red, violet, pink, orange, and grey microspheres. This is one of our core product lines and we welcome requests for custom colors and/or custom densities between 0.98g/cc and 1.2g/cc, which are often used for medical technology applications.

We ship microspheres worldwide on a daily basis!

Clear (translucent) microspheres and spheres in variety of formulations (polyethylene, poly(methyl methacrylate), solid and hollow glass). High index of refraction in barium titanate glass microspheres.
Opaque white spheres and microspheres in variety of materials and properties, including opaque white polyethylene, cellulose acetate, TiO2-coated spheres, zirconium oxide, silica, barium sulfate, polystyrene, polypropylene and more.
Fluorescent and non-fluorescent green spheres and microspheres are available in a variety of densities, sizes and formulations.
Whether used to trace the cardiovascular system of an animal or perform contamination studies on a critical process, high quality spherical red particles offer a versatile tool for scientific investigation.
Highly-spherical and colorful plastic particles are a useful tool as reference particles in simulation experiments and are successfully used in vision systems and fluidized bed applications.
Grey microspheres of high sphericity and tightly defined particle size distribution are used in industrial and scientific applications for process control, diagnostics, and medical device technology.
Bright orange microspheres help color code the particles to better understand which part of the process the spheres of the specific size were able to pass through, or where the contamination in the process is coming from.
Many options of this bright highly visible marker. Some yellow particles were specifically designed with density of 1g/cc for suspension in fresh water, enabling flow visualization and PIV analysis of fluid flow in a device.
Bright blue spherical polymer particles are supplied in dry powder form and are color-stable in solution. Controlled particle size ranges enable investigation of maximum particle size passing through openings, filters and membranes.
Pink microspheres offer an additional option for color-coding experiments. Particles with density of 1.00g/cc offer exceptional performance as flow tracer or seed particles in Particle Image Velocimetry of aqueous solutions.
Violet (purple) spheres are available in fluorescent or non-fluorescent options. These spheres offer high visibility, sphericity, fluorescent response, and density designed for suspension.
