Our PASPORT Colorimeter records all 4 wavelengths simultaneously--no need to guess at wavelength to get a quality measurement. Digital circuitry handles the calculations, calibrations and adjustments – all you have to do is collect data. Simultaneously reports both absorbance and transmittance. Black, opaque housing eliminates ambient light to assure data accuracy.
Great for Beer's law experiments, absorbance vs. concentrations, and reaction rates.

  • Auto calibration – insert a cuvette of clear water, press one button and calibration for all wavelengths is done.
  • Samples 5 times a second - making rates of reaction experiments a reality.

Special Features

  • Stabilized light source for consistent readings
  • Simultaneously reports both transmittance and absorbance
  • Borosilicate cuvettes last longer than plastic and have greater optical clarity

Typical Applications

  • Study absorbance vs. concentration
  • Determine the concentration of an unknown solution (Beer's Law experiments)
  • Measure reaction rates

Includes

  • 5 Borosilicate glass cuvettes
  • Molded plastic storage case for sensor and cuvettes
  • Sensor Extension Cable
