FluoroMax Plus(ls)
Sensitive, Flexible, Trusted Spectrofluorometer
The FluoroMax® Plus represents HORIBA's industry-leading fluorometer performance in a convenient, affordable, easy-to-use benchtop model. The FluoroMax family, with its unique all reflective optics and photon counting was the first to bring the sensitivity of a modular fluorometer to a tabletop fluorescence instrument, in the 1990's.
It’s a compact spectrofluorometer, yet offers the ultimate sensitivity in fluorescence investigations as well as features not found in most table-top fluorescence detection systems.
The FluoroMax Plus is the latest generation of the original, high performance tabletop fluorometer, which offers extended performance with detection of emission spectra out to 1700 nm and (TCSPC) Time Correlated Single Photon Counting lifetime measurements as short as 25ps.
