Set your students up for success with the Go Direct Fluorescence/UV-VIS Spectrophotometer. Geared toward upper-level chemistry, this innovative device combines the functionality of a fluorometer with the power of a UV/VIS spectrophotometer. The Go Direct Fluorescence/UV-VIS Spectrophotometer allows students to conduct fluorescence data collection back-to-back with absorbance data collection in a single instrument. This supports quantum yield studies, quenching investigations, kinetics, Beer’s law, and simple fluorescence detection with samples such as quinine sulfate, DAPI, GFP, and tryptophan. Excitation LEDs included are 375 nm, 450 nm, and 525 nm—other wavelengths can be purchased separately. Inquire about custom wavelengths. To conduct emission spectra experiments, simply attach the Vernier Spectrophotometer Optical Fiber.

Additionally, the Go Direct Fluorescence/UV-VIS Spectrophotometer connects directly to a tablet, computer, or LabQuest®, offering students the flexibility to work with many technologies used in chemistry labs. Data can be collected and analyzed using our LabQuest 2, LabQuest 3,  Logger Pro® software, or free Vernier Spectral Analysis® software, which allows users to spend less time learning different interfaces and more time in the laboratory.
