Informations sur le produit "Fluorescence LED Cartridges - 280 nm"

For use with the Fluorescence/UV-VIS Spectrophotometer, this filter acts as an excitation source to cause the sample to fluoresce. Because the excitation source is an exchangeable LED, not only do you get the standard functionality of a spectrofluorometer but software controls allow students to determine the LED intensity and explore fluorescence as a function of excitation.

Available LED Cartridges:

VSP 280 nm LED
VSP 350 nm LED
VSP 375 nm LED
VSP 400 nm LED
VSP 450 nm LED
VSP 500 nm LED
VSP 525 nm LED

Vernier Fluorescence / UV-VIS Spectrophotometer

The affordable Fluorescence/UV-VIS Spectrophotometer is designed specifically for upper-level chemistry courses. Vernier International has 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.
