One-Stop Reliable Source of High Quality Microspheres

Cospheric is your one-stop reliable source for high quality microspheres, particle sizing, and analytical services. We also offer consulting and custom R&D services to develop and manufacture microsphere solutions to meet the unique needs of each customer. Most standard products are in stock and ship the same business day. NIST traceable measurements of particle size and density are available for most microspheres with the purchase of NIST traceable microsphere certificate of analysis. Place an order on-line or contact a microsphere expert for a custom quote.

1500+ SKUs of high quality microspheres in stock and ready to ship the same business day

We are constantly expanding the selection of NIST-traceable precision spheres, microspheres, beads and microparticles we have in-stock. Variety of colors, materials, densities, fluorescent, phosphorescent, paramagnetic, solid, hollow, coated, monodisperse, spacer grade, neutrally-buoyant, and density marker beads. Solid and hollow glass, silica, PMMA, polyethylene, and other polymer spheres, silver-coated glass, aluminum-coated retroreflective particles, TiO2-coated spheres and more unique beads in diameters from below 1micron to 3mm. 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 tracer particles and spheres for flow visualization studies.

Advantages of Cospheric Microspheres:

Cospheric offers a broad selection of high-quality well-characterized microspheres. Each microsphere product is highly spherical, listed with images and detailed technical descriptions, defined size ranges, and specific densities to the second and sometimes third decimal place.

Large selection of microsphere products allows you to place one order with lots of options for design of experiments, contamination studies, optimizing bond line spacing, and other R&D, engineering, and industrial projects. We offer multiple types of microspheres of the same size, multiple types of microspheres of the same density, multiple colors of microspheres in the same size and/or density. If you are not sure on which size you need for your application, there is a large selection of in-stock sizes to choose from, which are narrow and offer you the ability to determine what will work best for your application.

Custom capability for larger order quantity, specific size range, color, density, or specific properties, and a large selection of tight particle size ranges of coated microspheres offer endless customization possibilities.

Most orders (both domestic and international) ship the same business day. Quick and efficient on-line check-out with clearly stated prices and stock status enables you to place an on-line order for microspheres 24/7 anywhere in the world.

Custom Coatings on MicroParticles:

We can apply precision thin coatings on microspheres and have extensive experience with laminations, encapsulations, and adhesives (solvent resistant, optically clear, heat-sensitive or pressure-sensitive, activation temperature, etc). We own proprietary technology for applying hemispherical half-shell coatings on particles and arranging a monolayer of particles in an array or a specific pattern. We also have extensive experience in electronic paper development. Contact a microparticles expert to discuss your needs.

Particle Sizing and Classification Services:

We pride ourselves on tight particle size distribution of our products and offer custom particle size classification services to grade your particles, powders or aggregates to size. We are equipped to grade your particles to any size between 15um (0.00059 inches) and 5.6mm (0.220 inches). Spacer grade particles and custom particle sizes are possible and available by request. We utilize a very strict quality control process using Optical Microscopy to guarantee that the product is in spec and can provide a certificate of compliance per request.

Analytical Services:

Our testing lab provides measurement services for NIST-traceable Particle Size and Shape and Particle Size Distribution utilizing Optical or SEM Microscopy depending on the size of the particles. We can provide a technical report that includes high resolution images of your particles and a detailed analysis of results. Since we specialize in custom density microspheres and density marker beads, we are equipped to perform NIST-traceable Density Measurements of your particles with the most accurate gas pycnometer on the market.

Consulting Services:

There are many different particles on the market and the possibilities for custom formulated particles are endless . It can be hard to decide what materials, colors, densities, and particle sizes are suitable for your unique projects. In addition, specifications need to enable a cost-effective and economical solution that fits into the project's budget or meet projections for the price of the final product. Often the customer needs a reality check: Do these required particles exist or can they be manufactured? Can they be manufactured cost-effectively? How much investment in R&D is required? How long does it take to scale-up to product quantities? Our consulting services will help you answer these questions. Contact a microspheres expert to discuss your project.
