NEW Improved Spectrovis Plus
 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.
What’s New and Improved with SpectroVis Plus?
- Improved range: 380–950 nm (VIS-NIR)
- nm between reported values (now collects 570 values)
- Improved optical resolution (~2.5 nm)
- New support for fl uorescence (two excitation sources centered at 405 nm and 500 nm)
More Features
- Portable: 15 cm x 9 cm x 4 cm
- Collect a full spectrum in less than 1 second
- Easy one-step calibration
- Connects directly to LabQuest or to a
computer’s USB port
- No external power required
- Software required: Logger Pro 3.8.2 (or newer) or LabQuest App 1.4 (or newer)

Uses
- 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 fl uorescent bioassays
- Measure emissions of gas discharge tubes, fl ame tests, or other light sources, using the SpectroVis Optical Fiber (not included)
How Does it Work?
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
fl uorescence spectra of many compounds, such
as quinine, florescein, and chlorophyll. |
Order Code: VR100640 NEW Spectrum Tube Single Power Supply
 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. The
gas tubes are permanently enclosed in plastic
carriers that protect the tubes from breakage.
There are no through-the-glass electrodes, so
the tubes last far longer than older designs. The
Power Supply will energize one tube at a time
and includes storage space for an additional six
tubes. Order Code: VR109664
All spectrum tubes sold separately:
 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.
