The FP-8550 has the highest sensitivity and optimal spectral accuracy with a wide range of accessories for maximum flexibility in experimental design. 

A High Performance Spectrofluorometer

FP-8550 Spectrofluorometer

The FP-8550 Spectrofluorometer has been designed for demanding research applications and has the same functionality and advantages as the FP-8350, but also includes an optimized optical design for very low stray light and enhanced spectral purity. Combined with the most thorough spectral correction, material engineers and researchers are assured of accurate measurements for the evaluation of advanced materials. The FP-8550 performs with the highest sensitivity* for fast measurement of samples with low-level fluorescence, whether they are challenging biochemical systems or low quantum efficiency materials. High-speed scanning of phosphorescent samples and 3D spectra enables fast acquisition of high-quality, high-density data.

The FP-8550 optical bench has been developed to take advantage of the wide range of sampling accessories and applications, such as temperature-dependent melting and kinetics, anisotropy, FRET, spectral correction, and quantum yields.
