Bright fluorescent green 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 Green
Fluorescent Response: Peak emission of 515nm when excited at 414nm
Particles in Size Range: > 90%
Spherical Particles: > 90%
