Phosphorescent Yellow-Green Polyethylene Microspheres 1.04g/cc, 1.14g/cc - 20um to 600um
Description
Long-afterglow yellow-green phosphorescent 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.
Phosphorescent particles are used for process study and blind tests especially in medical technology industry, diagnostics, troubleshooting, process flow, medical research and other industries.
Particles exhibit a strong long-afterglow phosphorescent response and are 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.
