label: Description
content: Troemner displayed four counter balances based on “Hoffman’s patent” at the American Pharmaceutical Association meeting in 1867. Although he did not identify Hoffman, Troemner did note that, as was the case with the “French or Béranger balance,” the working parts were in a box, below the pans. And, having but a single beam, there were fewer bearings and thus less friction. The form proved remarkably successful.
