Balance or scale - Curie System

Arare and historically important scientific instrument: an aperiodic balance designed according to the work of Pierre Curie, a 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 century and the very beginning of the 20th century, intended for laboratory work requiring extreme stability and the elimination of parasitic oscillations. The aperiodic principle, directly derived from Pierre Curie’s research, marks a major technological breakthrough in the history of measuring instruments.
Scientific and historical interest
An iconic instrument in research around piezoelectricity, the precise measurement of forces and masses, and more broadly the foundations of modern experimental physics.
A typology of instruments that is now almost extinct, preserved mainly in museum, university, or institutional collections.
Direct material testimony to the work and influence of Pierre Curie, far beyond the role often reduced to that of Marie Curie’s husband.
Rarity
Aperiodic balances of this type are extremely rare on the private market.
The majority of known specimens are preserved in science museums, universities, or heritage collections.
Appearances at public auctions are exceptional, which makes them a serious opportunity for a collector, a museum, or a scientific institution.
Status and conservation
Instrument carefully preserved, in a condition consistent with its age.
Presence of the characteristic constitutive elements of the aperiodic device.
An object that has not been restored invasively, preserving the instrument's historical and material authenticity.
