Analytical Balance

Usage conditions apply
Analytical balance with a 5-inch beam, agate bearings, and wooden frame with glass sides. The inscription on the ivory scale reads: “SPOERHASE SUCC. TO C. STAUDINGER GIESSEN / A. H. THOMAS CO AGENT PHILADA 3481.” The “GESETZ GESCH.” inscription on the rider lift housing is German for legally protected.
Carl Staudinger of Giessen began making balances in 1842, showed his wares at international exhibitions, and was succeeded by Wilhelm Spoerhase in 1888. Arthur H. Thomas began bringing Staudinger / Spoerhase balances into the United States in 1899, and soon had supplied them to “practically every University, College and Technical School” in the country; in some institutions there were upwards of 75 instruments in actual use. The importation of these balances ceased with World War I.
