Fluorescent Polymer Microspheres (1-5um)

Fluorescent Tracer Microspheres 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. These dry fluorescent microspheres are ideal tracer particles for air, water or solvent dispersal. The small size, bright colors, low toxicity, and solvent resistance allow suitability for studying of powder dispersal, toxin ingestion, and as micro-fluidic tracers.

FM-series fluorescent microspheres have the following properties:

  • Dry powder 1-5 um diameter (~2 micron mean)
  • Thermoset amino formaldehyde polymer
  • Density of 1.3g/cc (1.3g/ml)
  • Hydrophilic - no surfactant required.
  • Solvent resistant to most solvents
  • High temperature capable, up to 225ºC
  • Non-toxic
  • Multiple colors for combined variable testing.

Solvent and Bleed resistance of FM Series:

SOLVENT SOLUBILITY BLEED

Mineral Spirits Insoluble Negligible
Toluene Insoluble Negligible
Xylene Insoluble Negligible
Ethanol Insoluble Negligible
Methanol Insoluble Considerable
2-Propanol Insoluble Moderate
Acetone Insoluble Considerable
Methyl Ethyl Ketone (MEK) Insoluble Considerable
Ethyl Acetate Insoluble Slight to Moderate
