SUMMARY

The device used to measure percent light absorption in pigments is a spectrophotometer. This user-friendly instrument allows users to insert sample tubes and receive numerical data on light absorption. The discussion references a specific model, the Spectronic 20, which is widely used in educational settings for experiments involving pigment analysis. Spectrophotometers are essential tools in biological and chemical laboratories for quantifying the concentration of substances based on light absorption.

PREREQUISITES
  • Understanding of light absorption principles
  • Familiarity with spectrophotometry techniques
  • Basic knowledge of pigment chemistry
  • Experience with laboratory equipment usage
NEXT STEPS
  • Research the operation and calibration of the Spectronic 20 spectrophotometer
  • Learn about the Beer-Lambert Law and its application in spectrophotometry
  • Explore different types of spectrophotometers and their specific uses
  • Investigate the role of pigments in photosynthesis and their measurement techniques
USEFUL FOR

Students in biology and chemistry, laboratory technicians, educators conducting experiments on light absorption, and researchers studying pigments in various applications.

What is the device used to measure percent light absorption in pigments?

I remember finding the percent light absorption in the pigments of some vegetables for a high school bio lab. I am pretty sure the device used was not specific for pigments. The device was user friendly- we just stuck some tubes in a magical box and the box displayed a number.
