摘要
The invention concerns a device for dosing at least a particular constituent in a product sample, comprising a receptacle (110) and a cover (120) assembled to form a closed container. The invention is characterised in that said container has a vertical axis (101), the receptacle and the cover bear coaxial cylindrical walls (111, 112, 113) defining concentric annular chambers (102, 103, 104) inside the container, the walls separating chambers each comprising an opening (11a, 112a), the cover and the container can rotate relatively to each other about the vertical axis and said openings are placed in predetermined manner so that by relative displacement of the walls, the openings are positioned in a straight line or offset to communicate or isolate said successive chambers. The invention also concerns a method for using such a device and an apparatus for implementing said method.
