New Vernier Go Direct Fluorescence Spectrophotometer (GDX-SPEC-FUV) Measurement range 220-850 nm
The Go Direct Fluorescence/UV-VIS Spectrophotometer is a small, lightweight spectrofluorometer for ultraviolet and visible light. It combines a fluorescence spectrometer with a UV-VIS absorption spectrometer. Interchangeable LEDs ensure that you get the exact excitation wavelength you need.
The Go Direct Fluorescence/UV-VIS Spectrophotometer allows students to perform fluorescence data collection back-to-back with absorption data collection in a single instrument. This supports quantum yield studies, quenching investigations, kinetics, the Beer-Lambert law, and simple fluorescence detection with samples such as quinine sulfate, DAPI, GFP, and tryptophan. The included excitation LEDs are 375 nm, 450 nm, and 525 nm – other wavelengths can be purchased separately. Inquire about custom wavelengths. To perform experiments with emission spectra, simply connect the Vernier Spectrophotometer Optical Fiber.
Furthermore, the Go Direct Fluorescence/UV-VIS Spectrophotometer can be directly connected to a tablet, computer, or LabQuest®, providing students with 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®, or the free Vernier Spectral Analysis® software, allowing users to spend less time learning different interfaces and more time in the lab.
