Abstract
The invention features an analysing device (1) comprising a body (2) in which are arranged or provided: an intake aperture (3) for a starting liquid sample, a liquid flow circuit (5) comprising at least one operating cell (6) for a processed liquid sample, obtained from all or part of the original sample, communicating with the said intake aperture (3), the said flow circuit defining, in at least two dimensions of the card, one determined geometric line, such that any alteration in the card orientation in a three-dimensional reference frame, causes the liquid to flow under gravity only, from one part of the said circuit to another,for instance from one side or another of the operating cell, (6) characterised in that, the flow circuit (5) is continuous, and looped on itself between the said aperture (3) and the said operating cell (6).
