摘要： A device (1) for mixing liquids of different viscosity or composition within at least one container (2) is proposed. Each container (2) comprises an inner chamber (3) with an enclosing wall (8) and a bottom (10); an external encasement (6); an interspace (9); and a transfer opening (11) located at a top side of the inner chamber (3). A mixing body (12) located in the inner chamber (3) comprises magnetizable material (13) or a permanent magnet (13') and is spaced apart from the wall (8). The mixing device (1) comprises a coupling body (16) that is movable in the interspace (9) in direction of a longitudinal axis (4) and alongside the wall (8). The wall (8) and the external encasement (6) are transparent to magnetic fields. The coupling body (16) is in magnetic working connection with the at least one mixing body (12). At least one acting permanent magnet (19) or acting magnetizable material (19') located outside the external encasement (6) is in magnetic working connection with the coupling body (16). Moving the at least one acting permanent magnet (19) or acting magnetizable material (19') parallel to the longitudinal axis (4) of the inner chamber (3) simultaneously induces movement of the coupling body (16) inside the interspace (9) and moving the at least one mixing body (12) in the inner chamber (3), thereby mixing of liquids present in the inner chamber (3) of the container (2) is performed.

摘要： A displacement device for displacing a displacement volume is provided. The device comprises a first fluid space and a second fluid space. A first piston is arranged in a movable manner within the first fluid space. The first fluid space is connectable to a pipetting device. The first piston is actuatable by an actuation volume of air or of liquid provided by the pipetting device. A second piston is arranged in a movable manner within the second fluid space. The second piston is constructed to displace a displacement volume of a fluid located within the second fluid space when the second piston is actuated. The second piston is actuated in dependence on the first piston that is actuated by the actuation volume. The actuation volume is different from the displacement volume.

摘要： A device for mixing liquids in a container having an inner chamber with an enclosing wall and a bottom, an external encasement, an interspace and a transfer opening on top of the inner chamber. A mixing body located in the inner chamber comprises magnetizable material or a permanent magnet spaced from the wall. A coupling body movable in the interspace along a longitudinal axis and wall has magnetic working connection with the mixing body. The wall and the external encasement are transparent to magnetic fields. An acting permanent magnet or magnetizable material outside the external encasement, is in magnetic working connection with the coupling body. Moving the acting magnet or magnetizable material parallel to the longitudinal axis induces movement of the coupling body inside the interspace and moving the mixing body in the inner chamber, mixes liquids present in the inner chamber.

摘要： A method for determining physical parameters of a liquid (22) to be aspirated and/or dispensed by a laboratory automation device (10) comprises: pickup of a pipette (14) with the laboratory automation device (10); lowering the pipette (14) into a sample container (18) with the laboratory automation device (10), the sample container (18) containing the liquid (22); aspirating and dispensing air and liquid (22) with the laboratory automation device (10) in such a way, that a liquid level in the pipette (14) solely rises in a first step and solely lowers in a second step, such that an interior surface of the pipette (14) is wetted with liquid solely one time; and during aspirating and dispensing air and liquid (22), measuring a pressure curve (40) in the pipette (14) and determining the physical parameters from the pressure curve (40), the physical parameters comprising at least one of a surface tension, a wetting angle and a viscosity.
