Description
A Westphal balance was designed to measure the buoyancy of an object by weighing that object in air and then in water. The form was devised by a German pharmacist, Karl Friedrich Mohr, and improved by Georg Westphal (1836-1902), a balance and philosophical apparatus maker in Celle. This example was used by Dr. Jacques Loeb at the Rockefeller Institute for Medical Research in New York City.
