Custom Janus Particles, Microspheres, Microbeads – Bichromal Particles

Custom Janus Particles - Ceramic

What are Custom Janus Particles? Janus particle is anisotropic and refers to a particle, typically of spherical shape, with two hemispheres which may vary in color, optical properties, surface tension, electrostatic charge, magnetic response, conductivity, fluorescence, reflectivity and more. Custom Janus Particles Manufacturing Cospheric LLC uses a patented process to offer a unique capability of manufacturing custom Janus particles…

PIV Seeding – Microparticle Recommendations

Flow Visualization can best be accomplished with colored or fluorescent tracing particles of the same density as the fluid being studied. Very bright fluorescent micro-particles are available in densities of 1g/cc these offer not only bright testing under daylight conditions, but also the option of illumination with lasers or uv lights for increased system contrast.

High Density Glass Microspheres

Barium Titanate Glass microspheres are high density solid glass spheres. At a Density of 4.5g/cc these solid glass spheres can be used for many scientific applications where high density and optical clarity is needed. In addition to high density they also offer an index of refraction of more than 1.9.

Density Marker Beads – Microspheres with Specific gravity of 1.065 and 1.075

In the biomedical industry researchers are sometimes looking for cells having targeted specific gravities. In order to locate these cells in test tubes it is useful to have colored marker beads which will show where the delineation between specific densities occurs. Two microsphere products having densities of 1.065 g/cc and 1.075 g/cc were recently released. These…
