Disclosed are systems and methods for a mixing device having a mixing chamber bounded by an inner surface of a wall, the wall having a cylindrical outer face and at least one feed duct which ends on one side with an opening in the cylindrical outer surface of the wall and on the other side with an opening in the inner surface of the wall. The mixing device also includes a magazine having a cylindrical inner surface, the cylinder axis of which is coaxial with a cylinder axis of the cylindrical outer surface of the wall, and a multiplicity of ducts. The magazine and wall are movable with respect to one another such that the openings of the multiplicity of ducts in the inner surface of the magazine are each connectable in a medium-conducting manner to the opening of the at least one feed duct in the outer surface of the wall.

Mixing device and method for mixing media

The invention relates to a liquid supply interface for a cell culture system for supplying cell cultures found in different cell culture containers with a nutrient medium, wherein the liquid supply interface comprises: a housing defining a flow area; a first connection formation for the liquid-transferring connection of a first fluid line to the housing; a second connection formation formed separately from the first for the liquid-transferring connection of a second fluid line to the housing; a third connection formation formed separately from the first two for the liquid-transferring connection of the housing to a third fluid line; a coupling formation formed separately from the connection formations, which is formed for the producible and detachable liquid-transferring coupling contact according to the operation, with a corresponding counter-coupling formation of a cell culture container.

The invention relates to a liquid supply interface ('&#x2033;) for a cell culture system for supplying cell cultures found in different cell culture containers (&#x2033;) with a nutrient medium, wherein the liquid supply interface (&#x2032;&#x2033;) comprises: a housing () defining a flow area (); a first connection formation () for the liquid-transferring connection of a first fluid line () to the housing (); a second connection formation () formed separately from the first for the liquid-transferring connection of a second fluid line () to the housing (); a third connection formation () formed separately from the first two for the liquid-transferring connection of the housing () to a third fluid line; a coupling formation () formed separately from the connection formations (), which is formed for the producible and detachable liquid-transferring coupling contact according to the operation, with a corresponding counter-coupling formation () of a cell culture container (&#x2033;).

A solenoid valve unit is described for shutting off or enabling a throughflow of a medium along a hollow duct, which flows under application of pressure along the hollow duct, having at least one first magnet unit which is fixedly arranged along the hollow duct, which is implemented in the form of a hollow cylinder and is arranged in an axial section along the hollow duct in such a way that the first magnet unit radially completely surrounds the hollow duct and has a flow opening, which is circular in cross-section, on its downstream end, as well as a second magnet unit, which is mounted so it is movable to the first unit and is implemented as a ball, whose ball diameter is greater than the flow opening diameter of the first magnet unit and which, on account of an attractive magnetic force prevailing between both magnet units, can be brought into indirect or direct contact with the first magnet unit and seals the hollow duct in a fluid-tight manner, while the medium loads the first magnet unit under application of pressure opposite to the action direction of the magnetic force. A contour surface, which is angled in relation to a plane defined by the flow opening and surrounds the flow opening, and along which the spherical second magnet unit can be deflected axially and radially relative to the flow opening, indirectly or directly adjoins the flow opening, which is circular in cross-section.
