A Film Canister Colorimeter.
Gordon, James; James, Alan; Harman, Stephanie; Weiss, Kristen
Journal of Chemical Education, v79 n8 p1005-06 Aug 2002
A low-cost, low-tech colorimeter was constructed from a film canister. The student-constructed colorimeter was used to show the Beer-Lambert relationship between absorbance and concentration and to calculate the value of the molar absorptivity for permanganate at the wavelength emission maximum for an LED. Makes comparisons between this instrument and three commercial spectrometers and colorimeters. (Author/MM)
