Having an array spectrophotometer/fl uorometer combination<br />
is now affordable for each of your lab stations! SpectroVis plus<br />
spectrophotometer plus fl uorometer allows students to collect<br />
absorbance, transmittance, and fl uorescence data quickly<br />
and easily. in absorbance mode, you can quickly and easily<br />
measure the absorbance spectrum of a solution, concentrations<br />
of solutions, and rates of reactions. With its two different<br />
excitation wavelengths, SpectroVis plus can quantitatively<br />
measure the fl uorescence spectra of many compounds, such<br />
as chlorophyll, fl uorescein, GFp, and more. connect SpectroVis<br />
Plus to a LabQuest or a computer running Logger Pro using a<br />
standard USb cable (included), and see the results in full color.<br />
USeS<br />
• Measure absorbance spectrum of a liquid<br />
• Measure fl uorescence emission spectrum of a liquid<br />
• conduct beer’s law investigations<br />
• conduct kinetic studies of absorbance vs. time<br />
• conduct equilibrium studies of absorbance vs. time and/or<br />
absorbance vs. concentration<br />
• conduct experiments on enzyme kinetics<br />
• perform colorimetric or fl uorescent bioassays<br />
• Measure emissions of gas discharge tubes or other light<br />
sources using the SpectroVis Optical Fiber (not included)<br />
featUreS<br />
• portable: 15 cm x 9 cm x 4 cm<br />
• easy one-step calibration<br />
• Measures absorbance over a 380–950 nm range<br />
• ~2.5 nm optical resolution, 570 wavelengths, 1 nm reporting<br />
intervals<br />
• Fluorescence excitation centered at 405 nm or 500 nm<br />
• powered by computer or labQuest USb port; no additional<br />
power source needed<br />

Turn your SpectroVis Plus into an emissions spectrometer using<br />
the SpectroVis Optical Fiber insert. Simply insert the unit into the<br />
cuvette holder and point the 1 m optical fi ber at a light source.<br />
