notes: label: Description (Brief)
content: Fermentation saccharometers were used to estimate the amount of sugar in urine and diagnose diabetes. A small amount of yeast was mixed with 10cc of urine and then poured into the bulb of the saccharometer. The apparatus was then tilted slightly to allow the liquid to flow into the graduated tube and force the air out. If sugar was present in the urine, alcoholic fermentation would begin. The carbon dioxide gas created in the fermenting process would rise to the top of the closed tube and force the level of liquid down. The changed level of the liquid corresponded to the approximate quantity of sugar present. The percentage of sugar could be read off the graduated scale on the closed tube side of the apparatus.
