} • Vol. 82 No. 9 September 2005 • Journal of Chemical Education 1399 Efforts to modernize physical and analytical chemistry teaching laboratories are often hampered by a lack of funds, but it is possible for students, as part of their laboratory course or for advanced projects, to construct scientific instrumentation that can subsequently be used in experiments. Examples include the construction of a simple spectrophotometer (1) or the design and construction of a three… Expand
