This series of photographs may have been created in a laboratory in Japan. The set includes various views of the glucose analyzer, sample cell, pump, stirrer, oxygen sensor, check valve, and syringe. Descriptive captions are written in English. The first page includes some text in Japanese as well as three names: T. Nagata, Y. Takahashi, and Y. Fukumoto.
The Glucose Analyzer was developed by James Sternberg in 1969 and was one of several very successful medical testing and analysis instruments that Beckman Instruments produced in the 1970s. Its size, speed, and price enabled doctors to get fast, in-house results, instead of sending patients’ blood samples to a lab and awaiting a report.
