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.

Fluorescent microspheres are recommended for applications such as microcirculation and biological research, imaging and flow cytometry, which require the particles used to emit distinctive colors when illuminated by UV light. They offer additional sensitivity for observation through the use of microscopes, lasers and other analytical methods. Fluorescent microspheres can be excited and detected by a wide range of methods and are useful as experimental particles for acoustic and optical analytical systems.

Cospheric's fluorescent polymer microspheres are available in many particle sizes, colors, densities, and excitation and emission wavelengths, can be stored at room temperature or dispersed in aqueous media without degrading their fluorescent properties. The fluorophore is embedded into the polymer matrix to ensure that it will not leach out and will not diminish performance over time.
