New Improved Vernier Spectrovis Plus
Part of the New Organic Chemistry Range
An Affordable Spectrophotometer and Fluorometer
Having a CCD Array Spectrometer/Fluorometer combination is now affordable for each of your lab stations! Array spectrometer technology allows you to collect a full wavelength spectrum, Absorbance, Percent Transmittance, or Intensity in less than a second. Once the peak wavelength is determined, you can easily determine the concentration of a solution (Beer’s law) or monitor rates of reaction.
With its two different excitation wavelengths, SpectroVis Plus can quantitatively measure the fluorescence spectra of many compounds, such as chlorophyll, fluorescein, GFP, and more.
Connect SpectroVis Plus to a LabQuest or a computer running Logger Pro using a standard USB cable (included), and see the results in full colour.

Helium emission spectrum
Fluorescence spectra of Green Fluorescent Protein and Chlorophyll
Light from our long-lived LED light source passes through a solution. Emerging light goes through a high-quality diffraction grating then the diffracted light is collected and sorted by the CCD array detector.
With its two different excitation wavelengths, SpectroVis Plus can quantitatively measure the fluorescence spectra of many compounds, such as quinine, florescein, and chlorophyll.
SpectroVis Optical Fibre
Turn your SpectroVis spectrophotometer into an emissions spectrometer using the SpectroVis Optical Fibre insert. Simply insert the unit into the cuvette holder and point the 1 m optical fibre at a light source. Sold separately.
