Bright fluorescent green spherical particles are supplied in dry powder form. Controlled particle size ranges enable investigation of maximum particle size passing through the openings, filters and membranes. Particles exhibit a strong fluorescent response and are color stable in solution.
These spheres closely resemble the density of blood plasma at 1025 kg/m3.
Other colors, sizes and grades of fluorescent particles are available:Fluorescent Polymer Particles, Beads, Microspheres
Daylight Color: Fluorescent Green (515nm Peak)
Fluorescent Response: Peak emission of 515nm when excited at 414nm
Particles in Size Range: > 90%
Spherical Particles: > 90%
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.
