User manual

SpectroVis Plus is an affordable, portable, visible to near-IR spectrophotometer and fluorometer.

Description

SpectroVis Plus is a portable and affordable visible light spectrophotometer with fluorescence capabilities. Measure wavelengths from 380 nm to 950 nm and analyze results in full color.

Tech & Learning Award of Excellence 2011 Winner The SpectroVis Plus educational spectrophotometer combines fluorescence capabilities with a linear CCD array detector in an award winning, compact unit that requires no external power supply. Two different excitation wavelengths enable analysis of compounds such as fluorescein, chlorophyll, or GFP.

  • Connect SpectroVis directly to LabQuest or a computer USB port.
  • Set up experiments quickly with one-step calibration.
  • Collect data in under one second with array spectrometer technology.
  • Analyze full-wavelength spectrum data in full-color with Logger Pro.

Spectroscopy with SpectroVis Plus

SpectroVis Plus enables a wide range of introductory spectroscopy experiments for chemistry, biology, and physics.

  • Determine peak wavelength to collect data on solution concentration for studies of Beer’s law or to monitor rates of reaction.
  • Collect a full wavelength spectrum to measure absorbance, percent transmittance, fluorescence, or emissions.
  • Conduct enzyme kinetics experiments.
  • Engage in equilibrium studies of absorbance vs. time or absorbance vs.concentration.
  • Perform colorimetric or fluorescent bioassays.
  • Use the SpectroVis Optical Fiber Accessory to measure emissions from flame tests or other light sources. For more detailed emissions analysis, consider the Vernier Emissions Spectrometer.

How SpectroVis Plus Works

SpectroVis employs an LED and tungsten bulb to transmit light through a solution containing the sample. The transmitted light then passes through a high-quality diffraction grating and the diffracted light is sorted and collected by the linear CCD array detector.
