    Improve sensitivity and detectability for analytical methods with Thermo Scientific™ Fluoro-Max Green Aqueous Fluorescent Particles, microsphere suspensions that are internally dyed and feature bright, high-contrast colors.

    Fluoro-Max fluorescent particles emit bright and distinct colors when illuminated by the light of shorter wavelengths than the emission wavelength, improving their contrast and visibility relative to background materials.These internally dyed polymer particles utilize the exclusive Firefli™ process to incorporate the dye throughout the polymer matrix to produce bright fluorescent colors, minimize photo bleaching and prevent dye leaching into aqueous media.


    • Made of polystyrene (PS), which has a density of 1.05g/cm3 and a refractive index of 1.59 @ 589nm (25°C)
    • Aqueous suspensions are packaged as 1% solids
    • Can be detected with an epifluorescence microscope, confocal microscope, fluorometer, fluorescence spectrophotometer or fluorescence activated cell sorter
    • Can also be detected using mineral light or black light (UV)

    Spectral information is approximate and for reference only. Spectral properties of the dyes are dependent on their concentration and physical environment.The exact excitation and emission maxima may vary depending on the size and composition of the particles.
