Visible Spectroscopy (380–950 nm)
Generates full spectrum, Beer’s law graph, and kinetics traces of visible samples such as food coloring, nickel sulfate, and crystal violet
Ultraviolet Spectroscopy (220–850 nm)
Generates full spectrum, Beer’s law graph, and kinetics traces of ultraviolet and visible-absorbing samples such as aspirin, DNA, proteins, and NADH
Fluorescence Spectroscopy
Measures the fluorescence and absorbance spectra of ultraviolet and visible samples such as quinine sulfate, fluorescein, rhodamine, and DAPI
Emissions Only Spectroscopy (350–900 nm)
Designed for emissions spectra from light bulbs, gas discharge tubes, or the sun
Flash Photolysis Spectroscopy (450–750 nm)
Measures the absorption or emission changes over time of a photo-excited sample at a single wavelength
Colorimeter
Our 4-wavelength Colorimeter is a low-cost alternative to a spectrophotometer. Measure absorbance versus concentration or absorbance versus time at 430 nm, 470 nm, 565 nm, or 635 nm.
Reflectance Spectrometer
ALTA® II Reflectance Spectrometer is a rugged, simple classroom instrument, designed to help students learn about light, color, and spectroscopy. Students can easily and rapidly collect data on the proportions of colored light (including infrared) that reflect from real-world objects.
