Vernier Spectrometer

The Vernier spectrometer, powered by Ocean Optics™ technology connects directly to your computer with a standard USB cable. It is a fully functioning visible light spectrometer giving precise measurements instantly over a range of 380-950 nm.

Use the Vernier spectrometer to:

• Measure the absorbance spectrum of an aqueous sample
• Conduct Beer’s Law experiments at one or more wavelengths simultaneously
• Conduct kinetic studies of absorbance vs. Time at one or more wavelengths
• Conduct equilibrium studies of absorbance vs. Time and/or absorbance vs. Concentration
• Conduct emission spectrum analysis with the fibre optic assembly.

Key Features of the Vernier Spectrometer

• The Vernier Spectrometer is a truly portable device measuring 10 cm x 9 cm x 3 cm.
• One-step calibration of the full spectrum saves precious lab time.
• A complete visible light spectrum, 380-950 nm, is collected in a fraction of a second.
• The open cuvette holder allows for access to the sample during testing.
• Other Vernier sensors can be used simultaneously with the Vernier Spectrometer expanding your students’ opportunities to pursue a variety of research products.
• The Vernier Spectrometer draws its power from your computer, eliminating the need for an additional power source.
• Works with many Ocean Optics products
• Does much more than other spectrometers at a lower price (and size!).

A full analysis of crystal violet solution. The spectrum analysis (top graph) identifies the absorbance peak, from which a Beer’s law plot is completed. The bottom graph displays the absorbance vs. Time of the reaction of crystal violet and NaOH solution.
