Fluorescent

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.
