Microspheres, Microstructures, Particle Sizing, Custom R&D
Cospheric is your one-stop reliable source for microspheres, microstructures, particle sizing and
analytical services. We also offer consulting and custom R&D services to develop and manufacture microtechnology solutions to
meet unique needs of each customer. Most standard products are in stock and ship the same business day. Place an order on-line or contact us for a custom quote.
We are constantly expanding the selection
of 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 and flow visualization studies.
Polymeric microstructures are manufactured by microreplication
or microembossing technology with high or low
aspect ratio precision microstructured geometries in a variety of
polymer films, and are widely used in medicine, optics, and biotechnology. Polycarbonate (PC) and polyetherimide (PEI)
films as thin as 50micron are used to make microreplications of greater than 5:1
aspect ratios and ~250k features per square inch. High
aspect ratio microreplications of greater than 10:1 are possible.
Custom Coatings on MicroParticles and MicroStructures:
We can apply precision thin coatings
on microspheres and microstructures
, 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 us
to discuss your needs.
