A dual centrifuge (10) embodies the following: a driveshaft (16), a rotor (20), which is mounted on the driveshaft (16) and which can be removed axially in a removal direction (E), for a dual centrifuge, having at least one rotational unit (30); an opening (18) in the rotor (20), wherein an end region (16a) of the driveshaft (16) at least engages into said opening; and an additional drive mechanism (32) for the rotational unit or the rotational units (30). The dual centrifuge additionally has a design for operating various additional types of rotors; however, only one rotor (20, 40, 50) can be arranged on the driveshaft (16) at all times. The various rotor types (40, 50) are also adapted to the additional drive mechanism (32) for the rotational units (30) such that the function is not adversely affected. A design for operating at least one angular head rotor (40) and a swing-out rotor (50). For this purpose, the driveshaft (16) and the various rotor types (40, 50) are adapted to each other. The bearing (16), the driveshaft (16), and the various rotor types (40, 50) are adapted to one another such that each non-dual rotor (40, 50) has a geometry that is measured such that when the rotor (40, 50) is mounted, a drive device (32a) of the additional drive mechanism (32) for the rotational units (30) is arranged so as to not contact the mounted rotor (40, 50).

A centrifugal processing unit for directing the movement of substances within a sample processing cartridge having a rotor for receiving the sample processing cartridge, a rotor drive to create a centrifugal force, the centrifugal processing unit having a pivot accommodation and a fix accommodation for receiving the sample processing cartridge that are arranged on the rotor, where each pivot accommodation being adapted to allow a free pivoting motion of the received sample processing cartridge about a respective pivot axis, and each pivot axis being orthogonal to the rotor axis to the respective force vector of the centrifugal force.

A system for separating biological material includes a centrifuge tube, a separation tube having an open bottom, a cap, and a separation medium disposable within the centrifuge tube and the separation tube. The centrifuge tube and the separation tube sealingly and releasably couples to the cap, such that, when coupled, the separation tube is positioned within the centrifuge tube. The cap is configured to facilitate and/or regulate air- or gas-flow between an area outside of the cap and an interior of the separation tube. When the separation tube is positioned within the centrifuge tube, the open bottom of the separation tube is submersed in the separation medium. The system also includes a hollow needle coupled to a means for regulating a flow of air, gas, or other matter. The needle is insertable through the cap or plug, and is used to facilitate the introduction of matter into the separation tube.

Embodiments described herein include sample reservoir insert devices and methods of using and making the same. The embodiments can be used for the separation of bone marrow cells from murine and human specimens by centrifugal force. The devices can be sterile, single use rigid embodiments with an attached cap coupled to the sample reservoir insert with a hinge within which the specimens will be placed during the separation procedure.

A centrifuge rotor includes tube retainers for holding two or more sample tubes at a 90 degree angle in a minimized configuration for effective separation of a blood sample using a mini centrifuge. The centrifuge rotor with sample tubes in place has an overall width that is less than two times the length of a sample tube.

The invention relates to an arrangement for preparing a plurality of samples for an analytical method, comprising a carousel with a solid housing and moveable receiving parts for the sample containers; a control for controlling the receiving parts in the carousel; and a sample receiving device for providing the sample for the analytical method.
