Yellow Polyethylene Microspheres 1.00g/cc - 10um to 500um (0.5mm) - Strong Negative Charge
Description
Bright yellow polymer microparticles of high sphericity and tightly defined particle size distribution are used in industrial and scientific applications for process control, diagnostics, and medical device technology. These spherical polyethylene beads are specifically designed with density ~1g/cc for suspension in fresh water, enabling flow visualization and PIV analysis of fluid flow in a device. It is often advantageous to color code the particles by size to better understand which part of the process the spheres of the specific size were able to pass through, or where the contamination in the process is coming from.
Other colors, sizes and grades of polyethylene spherical particles are available:
Polyethylene Microspheres (Colors, Fluorescent, Phosphorescent, Barium Sulfate)
Other neutrally buoyant particles for flow visualization and PIV are available:
Microspheres for Flow Visualization and PIV (1.0g/cc)

· Particles in Size Range: > 90%
· Spherical Particles: > 90%
· Charging: High Negative Charge
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.
Microspheres are supplied in dry powder form and are color stable in solution. No solvents are used in the manufacturing process. Polyethylene is inert to most solvents.
