The invention refers to a filter (23, 24) a cartridge (9) containing a particulate material (20), a use of the filter and a system for preparing a liquid solution. The cartridge (9) includes an inner space (10) for housing the particulate material (20), an inlet (21) arranged to permit the introduction of a liquid into the inner space, and an outlet (22) arranged to permit discharge of liquid from the inner space. The filter (23) is arranged at the outlet (22) to permit passage of the liquid in a filter direction (x) through the filter but to prevent passage of the particulate material through the filter. The filter includes at least one slit-shaped opening, which has a first extension and a second extension being substantially perpendicular to the filter direction (x). The second extension is significantly shorter than the first extension.
L'invention concerne un filtre (23, 24), une cartouche (9) contenant une matière particulaire (20), l'utilisation du filtre, et un système de préparation d'une solution lilquide. La cartouche (9) comprend un espace intérieur (10) destiné à recevoir la matière particulaire (20), une entrée (21) permettant l'introduction d'un liquide dans l'espace intérieur, et une sortie (22) permettant l'évacuation du liquide de l'espace intérieur. Le filtre (23) est positionné au niveau de la sortie (22) afin de permettre le passage du liquide dans le filtre dans une direction (x) du filtre, tout en empêchant le passage de la matière particulaire dans le filtre. Le filtre comprend au moins une ouverture en forme de fente, présentant une première extension et une seconde extension sensiblement perpendiculaire à la direction (x) du filtre.
