Abstract:
A device for qualitative and/or quantitative dosing of at least one particular component in a product sample by labeling and fixing, said device comprising a container and a cover which are connected to form a closed receptacle, wherein said closed receptacle has a vertical axis, the container and the cover carrying coaxial cylindrical walls which, while the container and cover are being connected, position themselves pairwise one against another thereby delimiting at least three concentric annular chambers inside the receptacle, namely from the axis an inlet chamber for receiving the sample and allowing labeling of the component, a chamber for fixing and reading said labeled component, and a discharge chamber, the coaxial cylindrical walls forming separations between successive annular chambers each having at least one opening, and the connected cover and container being relatively rotatable about the vertical axis, and the openings of the coaxial cylindrical walls of the container and of the cover being placed at predetermined angular positions in such a way that by displacement of one with respect to the other of the cylindrical walls of each pair, the openings of each pair of walls are able to be positioned opposite one another or in an angularly offset manner, so as to put into communication or isolate from one another the successive annular chambers.
