Cospheric LLC Fluorescent Red Polyethylene Microspheres 1.050g/cc - 45um to 500um (0.5mm)

Cospheric Fluorescent Red Polyethylene Microspheres 1.050g/cc - 45um to 500um (0.5mm) are bright fluorescent red microspheres 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. 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.
