Bright fluorescent orange 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. 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 Orange (606nm Peak)
Fluorescent Response: Fluorescent Orange under 300-600nm wavelengths. Works well with Green Lasers. Peak emission of 606nm when excited at 577nm
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.
