Fluorescent Microspheres

Fluorescent microspheres are round spherical particles that emit bright colors when illuminated by UV light. Ability to emit intense color under UV (black light) illumination provides contrast and visibility of microspheres relative to background materials. In addition to the benefits of conventional high quality microspheres, such as sphericity and smoothness, fluorescent spheres offer sensitivity and detectability for analytical methods.

Typical applications of fluorescent spheres include: testing of filtration media and systems, vial and container cleaning studies, flow tracing, flow visualization, medical imaging and flow cytometry, fluorescence microscopy, biomedical technology research, qualification and validation of medical devices, biomedical diagnostics, process troubleshooting and process flow among others. Specifically fluorescent microspheres are often used for water- and air-flow testing and bead-based diagnostic applications.

Cospheric's fluorescent polymer microspheres available in many particle sizes, colors, densities, and excitation and emission wavelength, can be stored at room temperature or dispersed in aqueous media without degrading their fluorescent properties.

CATEGORIES
Fluorescent powders 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.
UV fluorescent microspheres (particles, beads) in sizes from 10um to 1.4mm offer numerous opportunities in research and development and diagnostic applications. Microspheres are manufactured from pure polyethylene ensuring that fluorescent materials are completely embedded in the polymer matrix with no possibility of leaching out or degrading over time.
Solid glass, polymer or ceramic microspheres are hemispherically coated with fluorescent coating, which makes the spheres appear colorful and fluorescent at daylight and exhibit bright fluorescent response under UV light.
