Identifying an Unknown Analgesic by Three Methods Synthesis of Methyl Orange and Its Application to Textiles The Diels-Alder Reaction of Anthracene with Maleic Anhydride Synthesis of Dibenzalacetone by Aldol Condensation Fluorescence emission detection limit: 1 mg/L quinine sulfate dihydrate in 0.1 M H 2 SO 4Įxtraction of Spinach Pigments and Analysis by Electronic Absorption Spectroscopy.Sample format: 10 mm × 10 mm cuvette (UV fluorescence cuvette included).Absorbance photometric range (for best accuracy): 0.1–1.0.Absorbance photometric accuracy: ±5.0% (as determined with potassium dichromate NIST standards).Wavelength accuracy: ☒.0 nm (as determined with holmium oxide NIST standards).Optical resolution: 3.0 nm (as determined with 486 nm hydrogen emission spectral line FWHM).Emission light source: Exchangeable LED (ships with 375 nm, 450 nm, and 525 nm).Absorbance light source: Deuterium (UV) and incandescent (VIS).Power consumption: 3 A start-up, 500 mA continuous.Bluetooth power supply: USB (USB adapter Included).Lamp power supply: AC adapter (included).Experiment types: Full Spectrum, time-based (kinetics), and event-based (Beer’s law). ![]() Detection modes: Absorbance, Fluorescence, %Transmittance, Intensity, and Raw Lamp.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. Īdditionally, 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. To conduct emission spectra experiments, simply attach the Vernier Spectrophotometer Optical Fiber. Excitation LEDs included are 375 nm, 450 nm, and 525 nm-other wavelengths can be purchased separately. ![]() 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. 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. Geared toward upper-level chemistry, this innovative device combines the functionality of a fluorometer with the power of a UV/VIS spectrophotometer. Set your students up for success with the Go Direct Fluorescence/UV-VIS Spectrophotometer.
