Bright fluorescent yellow microspheres are supplied in dry powder form and specifically designed with density ~1g/cc for suspension in fresh 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.
Other colors, sizes and grades of fluorescent particles are available:Fluorescent Polymer Particles, Beads, Microspheres
Other neutrally buoyant particles for flow visualization and PIV are available: Microspheres for Flow Visualization and PIV (1.0g/cc)
Density: 0.99g/cc-1.01g/cc (perfect for suspension in water) Daylight Color: Fluorescent Yellow Fluorescent Response: Peak emission of 525nm when excited at 485nm Particles in Size Range: >90% Spherical Particles: >90%
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.
