The AMINCO-Bowman SpectrophotofluorometerPhoto of Dr Bowman in the lab with SPF device

In the 1950s, the NIH's Dr. Robert Bowman developed a sensitive instrument called the spectrophotofluorometer, or “SPF”, that allowed scientists to use fluorescence as a way to identify and measure tiny amounts of substances in the body.  This exhibit explores the instrument and its use in scientific studies ranging from anti-depressant medication to AIDS research and the Human Genome Project.
