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

Rhodamine B polyethylene microspheres appear pink in the daylight and are supplied in dry powder form. Rhodamine B particles of smaller sizes (<~100um) show a weak orange fluorescent responses, with 10-27um being the weakest. Larger Particles have a slightly better fluorescent response.

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: 0.98g/cc
Daylight Color: Pink
Illumination Color: Weak Orange response (Peak ~595nm)
Particles in Size Range: > 90%
Spherical Particles: >90%
Note: 710-850um, 850-1000um sizes are >75% spherical

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