Neutrally Buoyant in Water – Microspheres with Specific Gravity of 1g/cc

Suspension of microspheres in water enables the visualization and characterization of fluid flow and testing the capability of devices to withstand particulate matter in the fluid stream, ensuring that microspheres do not settle and do not float on the surface. Most of these polymer microspheres are at least moderately opaque and clearly visible in water, clear or translucent…

Phosphorescent Microspheres – Long Afterglow Particles

Phosphorescent microspheres in particle sizes 10 to 600 microns are now available from Cospheric LLC. These phosphorescent particles are 90% spherical and appear to be off-white under ordinary daylight or regular room illumination.? However, when the lights are turned off these phosphorescent particles exhibit phosphorescent yellow-green after-glow. The spheres have tight particle size distributions and are > 90% within…
