Beer's Law: Solution Absorbance and Concentration

Students use Chemvue software and either a Wireless Spectrometer (PS-2600) or a Wireless Colorimeter and Turbidity Sensor (PS-3215) to explore the relationship between solution color, concentration, and light absorbance (Beer's law), and then use that relationship to determine the unknown concentration of a solution.

Featured Equipment

Cuvettes and Caps

Replacement Polystyrene Cuvettes and Caps for the PASCO Wireless Spectrometer.

Wireless Colorimeter & Turbidity Sensor

This sensor can function as a turbidimeter or colorimeter and is capable of measuring absorbance and transmittance at six different wavelengths.

Wireless Spectrometer (Vis)

Measures intensity, absorbance, and transmittance across the visible spectrum. Includes fluorescent excitation at 405nm and 500nm.

Support

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
