Data Sheet - Polyethylene Spheres, Beads, Microspheres, and Nanospheres
Bright fluorescent blue microspheres 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.
Polyethylene microspheres are hydrophobic and need to be coated with a surfactant prior to suspending in water. We recommend Tween 80 Bio-compatible Surfactant.
