Product Summary
The Colorimeter Sensor allows a solution’s concentration to be determined based on the ability of the solution to transmit or absorb colored light. PASCO’s PASPORT Colorimeter is the perfect tool for analyzing reactions indicated by color changes, or reactions where concentration changes over time. The sensor’s black, opaque housing assures accuracy of data. The Colorimeter is packaged in a sturdy plastic case with five empty glass cuvettes so students can begin experimenting immediately.
Features
- Stabilized light source for consistent readings
- Simultaneously reports both transmittance and absorbance
- Borosilicate cuvettes last longer than plastic and have greater optical clarity
Applications
- Study absorbance vs. concentration (Beer’s Law experiments)
- Determine the concentration of an unknown solution
- Measure reaction rates
- Measure four wavelengths simultaneously
What's Included
- 1x 5 Borosilicate glass cuvettes
- 1x Molded plastic storage case for sensor and cuvettes
- 1x Sensor Extension Cable
