Fluorescent Green Polyethylene Microspheres 1.015g/cc - 10um to 1.4mm

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. Other colors, sizes and grades of fluorescent particles are available: Fluorescent Polymer Particles, Beads, Microspheres

Density: 1.01-1.02g/cc
Daylight Color: Fluorescent Green (515nm Peak)
Fluorescent Response: Peak emission of 515nm when excited at 414nm
Microspheres vs Micropellets vs Microparticles:
Microspheres: >90% of particles are spheres
Micropellets: >90% of particles are spheroids (sphere-like but not perfectly spherical body)
Microparticles: >90% of particles may have irregular shapes

Polyethylene microspheres, micropellets, and microparticles 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 usingTween 80 or Tween 20 Surfactants.
