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. Browse a large selection of microsphere products on-line or contact a microsphere expert for a recommendation or a custom quote. Place an order on-line 24/7. We ship microspheres worldwide on a daily basis!
