Material Safety Data Sheet - Polyethylene Spheres, Beads, Microspheres, and Nanospheres
Bright fluorescent yellow microspheres are supplied in dry powder form and specifically designed with density 1.02g/cc for suspension in salt water, enabling flow visualization and analysis of fluid flow in a device. 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 Surfacant.
Density: 1.01g/cc-1.03g/cc (for salt water suspension)
