Material Safety Data Sheet - Polyethylene Spheres, Beads, Microspheres, and Nanospheres

Bright fluorescent red 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.

Polyethylene microspheres are hydrophobic and need to be coated with a surfactant prior to suspending in water. We recommend Tween 80 Bio-compatible Surfactant.

Density: 1.20g/cc
Daylight Color: Fluorescent Red (607nm Peak)
Fluorescent Response: Fluorescent Red under 300-550nm wavelengths. Works well with Green Lasers. Peak emission of 607nm when excited at 575nm
Particles in Size Range: > 90%
Spherical Particles: > 90%

In-stock orders ship in 1-2 business days. Please contact us for custom size ranges or volume pricing.
