The invention relates to an apparatus (1) for removing and depositing micro-drops (2') of solutions from/on a surface (2), in particular chemical or biological solutions. The inventive apparatus comprises at least one micropipette or deposit point (3) which is mounted on a head (4) that can move in at least one direction, at least between one or more removal sites (5) and one or more deposit sites (6). Said apparatus is characterised in that the micropipette(s) (3) are mounted in the body of said head (4) and they can be moved in translation in relation to said head, by means of a device for controlling and limiting the application force of the micropipette(s) (3) on the deposit surface (2). Said controlling and limiting device is connected to a device for guiding said micropipette(s) in translation in relation to the head (4), while they are in contact with said surface (2) or in order to bring them into contact with said surface (2).

La présente invention a pour objet un appareil (1) de prélèvement et de dépôt sur une surface (2) sous forme de microgouttes (2') de solutions, notamment chimiques ou biologiques, comprenant au moins une micropipette ou pointe de dépôt (3) montée sur une tête (4) mobile selon au moins une direction, au moins entre un ou plusieurs site(s) de prélèvement (5) et un ou plusieurs site(s) de dépôt (6). Appareil caractérisé en ce que la ou les micropipettes (3) sont montées dans le corps de ladite tête (4), avec faculté de translation relative par rapport à cette dernière, par l'intermédiaire d'un dispositif de contrôle et de limitation des efforts d'application de la ou des micropipettes (3) sur la surface de dépôt (2), associé à un dispositif de guidage en translation de cette ou ces dernières par rapport à ladite tête (4), lors ou en vue de leur mise en contact avec ladite surface (2).
