An apparatus for separating magnetic particles from a liquid which contains said particles, said liquid being contained in an elongated vessel (11) having a length axis (12), said vessel being arranged in a vessel holder (13) with its length axi (12) in a substantially vertical position, said vessel (11) having a tapered cross-section that diminishes towards the bottom of the vessel and a side wall (14) which has an outer surface which forms an angle with the length axis (12) of said vessel (11). This apparatus comprises a magnet (15) having a plane outer surface (16) and being adapted for being moved by transport means (17) along a motion path (25), said magnet (15) and said transport means (17) being so arranged with respect to said vessel (11) that over a portion of said motion path (25) said plane outer surface (16) of said magnet is in contact with a portion of said outer surface of said side wall (14) of said vessel (11), and transport means (17) for moving said magnet (15) between a first predetermined position and a second predetermined position along said motion path (25).
L'invention concerne un appareil permettant de séparer des particules magnétiques d'un liquide qui contient lesdites particules, ledit liquide étant contenu dans une cuve allongée (11) comportant un axe longitudinal (12), ladite cuve étant placée dans un support de cuve (13) avec son axe longitudinal (12) dans une position sensiblement verticale, ladite cuve (11) présentant une section conique qui diminue vers le fond de la cuve et une paroi latérale (14) qui comporte une surface externe formant un certain angle avec l'axe longitudinal (12) de ladite cuve (11). Cet appareil comprend un aimant (15) avec une surface externe plane (16) et adapté pour être déplacé par un moyen de transport (17) sur une trajectoire de déplacement (25), ledit aimant (15) et ledit moyen de transport (17) étant positionnés par rapport à ladite cuve (11) de telle sorte que sur une partie de ladite trajectoire de déplacement (25), ladite surface externe plane (16) dudit aimant est en contact avec une partie de ladite surface externe de ladite paroi latérale (14) de ladite cuve (11), et le moyen de transport (17) permettant de déplacer ledit aimant (15) entre une première position prédéterminée et une deuxième position prédéterminée sur ladite trajectoire de déplacement (25).
