Object Details
- Description
- A stalagmometer is a glass instrument that measures the surface tension of a liquid, and that was often used to determine alcoholic concentration. Isidor Traube (1860-1943), a chemistry teacher at the Technische-Hochschule in Berlin, devised the form in the 1880s. The “Verf. V. C. Gerhardt” inscription on this example refers to Carl Heinrich Gerhardt (1846-1907), proprietor of a chemical supply house in Bonn. The inscription on the case reads “C. Gerhardt / Marquarts Lager Chemischen Utensilien . . . / Bonn.”
