abstract: In the history of science, the alterations of laboratorial working conditions during a defined period of time and the processes leading to substitution of one instrument by another are not well reconstructed. With respect to electrophysiology between 1845 and 1910, the present article attempts to call attention to the relationship between the use of instruments in a laboratory, the change in these instruments and the change of local environments in which the laboratory was situated.
