Fluorolog-QM

Modular Research Fluorometer for Lifetime and Steady State Measurements

The HORIBA Fluorolog-QM™ series of modular research grade spectrofluorometers is the fourth generation of the world famous HORIBA Fluorolog, with the first Fluorolog introduced by Spex Industries in 1975.

The Fluorolog-QM represents the culmination of decades of HORIBA’s industry-leading experience in development and manufacture of the highest level of spectrofluorometer performance and versatility. The Fluorolog-QM, with its exquisite, optically perfect, all reflective optics, combined with a multitude of light source and detector options, and sample handling accessories, provides the highest sensitivity and greatest versatility of any spectrofluorometer.

The Fluorolog-QM can be enhanced to suit a broad array of luminescence experiments, with the industry’s most extensive list of optional accessories to expand capabilities and performance, to meet all of the most demanding research lab’s experimental needs. And when you purchase a Fluorolog-QM all of these enhancements and accessories can be added to your system at any later time as your needs change, or funds become available.

With thousands operating in universities and research labs around the world, and tens of thousands of publications, Fluorolog has proved itself to be the best choice for the most demanding steady state, time-resolved, TCSPC, PLQY and NIR research.
