FP-8550 Spectrofluorometer Optimized for Research Measurements in the UV-visible Region

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 has been designed for demanding research applications and has the same functionality and advantages of 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 enable 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.
