A wide array of instrumentation can be found in industrialand research laboratories.  However, mostof these instruments are unaffordable for many secondary schools anduniversities � preventing science and engineering students from attaining valuableworking experience before entering the labor force.  The Karl Fischer titrator, a widely used analyticaldevice, is used for the quantification of water in various substances includinglaboratory solvents, transformer oils, pharmaceuticals, cosmetics, and foodproducts.  A focus on small scaleinstruments has led to development of a relatively inexpensive Karl Fischertitration device for educational practice.  Working laboratory experimentswith the titration apparatus have been developed and integrated into thecurriculum of analytical chemistry at The PennsylvaniaState University.  Laboratoryexercises, validation results demonstrating the accuracy and effectiveness ofthe instrument, and possible future implications will be presented.
