Description

Our affordable Fluorescence/UV-VIS Spectrophotometer is designed specifically for upper-level chemistry courses. We’ve combined the functionality of a fluorometer with the power of a UV/VIS spectrophotometer to allow students to easily and accurately conduct numerous fluorescence experiments with compounds such as quinine sulfate, DAPI, GFP, and tryptophan. Exchangeable LEDs ensure you get the exact excitation wavelength needed for your experiment. To conduct emission spectra experiments simply attach the Vernier Spectrophotometer Optical Fiber.

The Fluorescence/UV-VIS Spectrophotometer connects directly to a computer or LabQuest. Data can be collected and analyzed using our Logger Pro software, so there is no need to train students on yet another instrument software.
