Balance or scale - Curie System

Rare scientific instrument and historically major: an aperiodic balance designed according to the works of Pierre Curie, founding figure of modern physics and scientific metrology.
This balance belongs to the category of very high-precision measuring instruments developed at the end of the 19th and the very beginning of the 20th century, intended for laboratory work requiring extreme stability and elimination of parasitic oscillations. The aperiodic principle, directly arising from Pierre Curie’s research, marks a major technological breakthrough in the history of measurement instruments.
Scientific and historical interest
Iconic instrument of the research conducted around piezoelectricity, the precise measurement of forces and masses, and more broadly the foundations of modern experimental physics.
Typology of instrument today almost extinct, preserved essentially in museum, university or institutional collections.
Direct physical testimony of the work and influence of Pierre Curie, well beyond his often reduced role as Marie Curie’s husband.
Rarity
Aperiodic balances of this type are extremely rare on the private market.
The majority of known specimens are kept in science museums, universities or heritage collections.
Public sale appearances are exceptional, making it a serious opportunity for a collector, a museum or a scientific institution.
Status and conservation
Instrument carefully preserved, in a state coherent with its age.
Presence of the characteristic constitutive elements of the aperiodic device.
Object not invasively restored, respecting the historical and material authenticity of the instrument.
