Abstract: A device for stirring at least one liquid includes a fluidics module rotatable about an axis of rotation, a liquid chamber for the liquid within the fluidics module, an introducer for introducing mutually separate phase volumes of a phase different from the liquid, said phase volumes having a different density than the liquid, into the liquid within the liquid chamber, and a driving device for subjecting the fluidics module to such a rotation that the phase volumes are moved radially inward or outward in relation to the axis of rotation through the liquid due to the different density of the phase volumes and of the liquid and due to the centrifugal forces caused by the rotation.

Abstract: A revolver component for a reagent vessel for a centrifuge and/or for a pressure-varying device includes a revolver housing which is able to be installed in the reagent vessel. Provided on the revolver housing is a guide structure, which is able to be contacted using at least one elevation provided on one reagent vessel part of the reagent vessel or provided on a further revolver component. The guide structure is developed in such a way that the revolver housing is able to be adjusted, with respect to the at least contacted reagent vessel part or with respect to the further revolver component into a first submotion along an axis and into a second submotion about the axis.

Abstract: A revolver component for a reagent vessel has at least one first chamber that is configured to be filled at least partly with at least one liquid. The first chamber is formed or fitted such that a first chamber filling volume that is configured to be filled with the at least one liquid is delimited by an expansion-variable boundary. The expansion-variable boundary has a spatial expansion that can be reversibly adjusted such that the filling volume is configured to be varied. Reagent vessel insert parts and reagent vessels are also disclosed. Methods for centrifuging a material and for pressure treating a material are also disclosed.

Abstract: A fluidics module rotatable about a rotational center includes first and second chambers and a compression chamber. First and second fluid channels are provided between the first and second chambers and the compression chamber, respectively. The flow resistance of the second fluid channel is smaller, for a flow of liquid from the compression chamber to the second chamber, than a flow resistance of the first fluid channel for a flow of liquid from the compression chamber to the first chamber. Upon rotation at a high rotational frequency, liquid is initially introduced from the first chamber into the compression chamber via the first fluid channel, so that a compressible medium is compressed within the compression chamber. Subsequently, the rotational frequency is reduced, so that the compressible medium within the compression chamber will expand and so that, thereby, liquid is driven into the second chamber via the second fluid channel.

Abstract: A mixer for insertion into a rotor of a centrifuge has a mixing trough and an obstacle device with at least one obstacle. The at least one obstacle is configured in order to influence the flow of a liquid present in the mixing trough. In response to a rotation of the rotor, with a specified incorporation of the mixer in a holder of the rotor, a spacing between at least one wall section of the mixing trough and the obstacle device is variable such that the liquid present in the mixing trough flows around the obstacle of the obstacle device.

Abstract: A reagent vessel insert for a reagent vessel for a centrifuge and/or a pressure varying device includes an insert housing formed such that the reagent vessel insert is insertable in a reagent vessel for a centrifuge and/or for a pressure varying device. The reagent vessel insert also includes at least one agitating element arranged in at least one interior volume such that a place and/or position of the at least one agitating element is changeable with respect to the insert housing. The reagent vessel insert is configured such that at least one material filled into the at least one interior volume is agitatable and such that, during an adjustment, at least one subunit of the at least one agitating element contacting at least one holding structure, by which the at least one agitating element is held in at least one semi-stable place and/or at least one semi-stable position.

Abstract: A reagent vessel insert includes an insert housing formed in such a way that the reagent vessel insert is configured to be inserted in a reagent vessel for a centrifuge and/or for a pressure varying device. The reagent vessel insert further includes at least one magnet arranged non-adjustably with respect to the insert housing and at least one adjusting element arranged in an interior volume of the reagent vessel insert. The at least one adjusting element is at least partially formed from a magnetically attractable material such that a magnetic force of attraction exerted by the at least one magnet on the at least one adjusting element is at least greater than a force of the weight of the at least one adjusting element. A method includes one or more of centrifuging and pressure treating a material using the reagent vessel insert or a reagent vessel.

Abstract: A turret component for a reagent vessel includes at least one vessel structure into which at least one liquid and/or pulverized material is pourable. The at least one vessel is formed on the turret component, and the turret component has at least one predetermined breaking point on at least one vessel base of the at least one vessel structure. A reagent vessel insertion part for a reagent vessel for a centrifuge and/or for a pressure varying apparatus includes the turret component and also includes an insertion part housing configured to enable insertion of the reagent vessel insertion part into a reagent vessel for a centrifuge and/or a pressure varying apparatus.

Abstract: A device for insertion into a rotor of a centrifuge has at least two bodies stacked one above the other in a stacking direction inside a housing. The housing is configured such that it can be inserted into a holder of the rotor of the centrifuge. With a correct reception of the device in the centrifuge, and upon a rotation of the rotor, a spacing of one of the at least two bodies in relation to the axis of rotation of the rotor is smaller than a spacing of another of the at least two bodies in relation to the axis of rotation of the rotor. A first of the at least two bodies has at least one first cavity and a second cavity and a second body of the at least two bodies has at least one first cavity.

Abstract: A mixer for insertion into a rotor of a centrifuge has a mixing trough and an obstacle device with at least one obstacle. The at least one obstacle is configured in order to influence the flow of a liquid present in the mixing trough. In response to a rotation of the rotor, with a specified incorporation of the mixer in a holder of the rotor, a spacing between at least one wall section of the mixing trough and the obstacle device is variable such that the liquid present in the mixing trough flows around the obstacle of the obstacle device.
