The Spectrophotometer: A demo and practice experiment

The spectrophotometer is an instrument used to measure the effect of a sample on a beam of light. We can learn a lot about a substance by studying the way it interacts with light. In this video, we'll demonstrate how to use a spectrophotometer to perform a basic experiment: determining the absorbance spectrum of red food coloring. Included in the video is a short animation that illustrates the inner workings of a spectrophotometer. Special thanks to Joe Issa and the Gaston College Biotechnology department for helping to make this video. Practice using a virtual spec https://www.ncbionetwork.org/educatio...
