This paper describes the instrumentation developed by Pierre Curie in the 1880s to perform very precise measurements of electric charge and very small currents. This system, developed 150 years ago, was almost as precise as most present digital electronic charge measurement apparatuses. Maria Skłodowska-Curie used the same Curie quartz-electrometric system during her research from the selection of the research subject to the final discoveries. The main experimental difficulties regarding the measurement of picoampere leakage currents generated by radioactive rays were presented. It was emphasized that the availability for Marie Curie of a precise ready-to-use electrostatic measurement technique played an important, if not decisive, part in her career and her research. A more general issue addressed here is that laboratory techniques are not only a prerequisite of modern scientific work, but in a great part influence knowledge production.
