Fluorescent Tracer Microspheres

These Fluorescent tracers are round spherical particles that emit bright colors which are broad spectrum excitable (300nm thru emission color). The ability to emit intense color under UV (black light) illumination provides contrast and visibility of microspheres relative to background materials.

All of our FM series fluorescent microspheres have the following properties.

  • Dry Powder 1-5 um diameter (~2 micron mean)
  • Proprietary Polymer (1.3g/cc)
  • Hydrophilic - no surfactant required.
  • Solvent Resistant to most solvents
  • High Temperature capable, up to 225ºC
  • Non Toxic
  • Multiple Colors for combined variable testing.

These dry fluorescent microspheres are ideal tracer particles for air, water or solvent dispersal. The small size bright colors, low toxicity, and solvent resistance allows excellent visability. Customer's have used these particles to simulate toxic powder dispersal, toxin ingestion, and as micro-fluidic tracers.
