Bright fluorescent orange microspheres are supplied in dry powder form. Fluorescent particles of known density and particle diameter range are often used in density-matching for flow visualization and analysis of fluid flow in a device. Particles exhibit a strong fluorescent response and are color stable in solution.
These spheres are also available in aqueous solution as Density Marker Beads.
Other colors, sizes and grades of fluorescent particles are available:Fluorescent Polymer Particles, Beads, Microspheres
Polyethylene microspheres are hydrophobic and suspend easily in oil-based solutions. They can also be suspended in aqueous solution if coated with a surfactant prior to suspending in water. We recommend using Tween 80 or Tween 20 Surfactants.
