The measuring cell is composed of at least one cavity hollowed in a block of chemically inert material or material made chemically inert at least at the surface. The cavity defines a first cylindrical space whose bottom is, over a reduced part of its diameter, extended by a second space defining the measuring chamber proper, of conical, frustoconical or substantially hemispherical shape. The first cylindrical space is designed to receive a measuring electrode terminated by a magnetic torus and, applied, and if necessary held by means of a ferromagnetic ring, against the latter, a membrane, while inlet and outlet ducts for the liquids to be assayed are formed in the block. The cell is especially useful for micro-assays of biological fluids.
