SpectroVis Plus

Available March 2010

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 one 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 color.

Uses for SpectroVis Plus

• Measure absorbance, percent transmittance, emissions spectra, or fluorescence
• Conduct Beer's law investigations
• Conduct kinetic studies of absorbance vs. time
• Perform equilibrium studies of absorbance vs. time or absorbance vs. concentration
• Conduct experiments on enzyme kinetics
• Perform colorimetric or fluorescent bioassays
• Measure emissions of gas discharge tubes, flame tests, or other light sources, using the SpectroVis Optical Fiber accessory (sold separately)

How Does It Work?

Light from the LED and tungsten bulb 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.

For fluorescence, SpectroVis Plus has two different excitation wavelengths, so now you can quantitatively measure the fluorescence spectra of many compounds, such as quinine, fluorescein, and chlorophyll.

SpectroVis Optical Fiber Accessory

Turn your SpectroVis Plus spectrophotometer into an emissions spectrometer using the SpectroVis Optical Fiber insert. Simply insert the unit into the cuvette holder and point the 1 m optical fiber at a light source. Sold separately.

The best part is the SpectroVis Optical Fiber costs only $69, making it very economical to add emissions experiments to your curriculum.

Spectrum Tube Single Power Supply Accessory

With ultra-safe design, this spectrum tube power supply will provide a simple means of viewing gas discharge spectral lines with any of our spectrometers. Unlike other designs, this system has no exposed high voltage.

Free Downloadable Spectroscopy Labs for SpectroVis Plus

We have free downloadable activities for your spectrometer! The experiments are ready-to-use or adapt them to your own curriculum.

SpectroVis Plus is available March 2010. Logger Pro software (computer) or LabQuest interface (standalone) is required and sold separately.

Limited quantities are still available. The original SpectroVis has no fluorescence, a visible-only wavelength range, and lower resolution, but also at a lower price!
