Orange polyethylene microspheres of high sphericity and narrowly graded particle size distribution are used in industrial and scientific
applications for process control, diagnostics, and medical device
technology. These spherical polymer particles are specifically designed with density of 1.00g/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. Particles with density of 1.015g/cc are great for applications were the density slightly heavier than water is desired.
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)
at 1.00g/cc the tolerance is between 0.99g/cc and 1.010g/ccat 1.015g/cc the tolerance is between 1.010g/cc and 1.020g/cc
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.
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.
