A system for buoyant separation includes a separation container. Additionally or alternatively, the system can include an automated instrument, one or more processing components, and/or any other components. A method for buoyant separation can include any or all of: manipulating the separation container; adding materials to the separation container; removing materials form the separation container; otherwise processing the separation container; and/or any other processes.

A rotor for use in a centrifuge, and a method for balancing the rotor. The rotor includes a plurality of apertures arranged circumferentially around the rotor's axis of rotation, each configured to selectively receive a weight. A critical speed is determined for the rotor, and an imbalance determined for the rotor at a test speed below the critical speed. A trial weight is installed in a reference aperture, and another imbalance determined at the test speed. The trial weight is repeatedly moved to another aperture angularly displaced from the previous aperture, and the imbalance measured at the test speed until a predetermined number of imbalance measurements have been obtained. A target mass and location for balancing the rotor is determined from the imbalance measurements, and balancing weights installed in apertures based on the target mass and location. The balancing process may be repeated for multiple critical frequencies.

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. Said arrangement is characterized in that one or more stations for preparing samples are provided on the carousel, the receiving parts for the sample containers of the carousel can be positioned on said stations. Said arrangement also comprises a centrifuge with pairs of opposite lying receiving parts provided for the sample containers, and said receiving parts are arranged such that they can move on the centrifuge for the sample holder such that a transfer of a sample holder between a receiving part in the carousel and a receiving part in the centrifuge can be carried out. The control takes place by the same control which is also provided for controlling the carousel.

The present invention may include an upper cap having an opening/closing member for opening and closing an inlet through which a blood is injected; a main body housing having an open upper end outer surface thereof assembled with the upper cap, and having an inner space in which the blood is filled with; an adjustment housing that is coupled to the main body housing to seal the open lower end of the main body housing, and is movably assembled with respect to the main body housing so that a buffy coat layer is positioned on a neck portion; and a side cap fixed to the neck portion by forming a needle hole through which an end of an injection needle for extraction enters and exits in area corresponding to a sealing member to seal an extraction hole formed through the neck portion.

This invention concerns a centrifugal device that houses adapters for commercial or scientific samples (or tubes containing such samples) and is manually operated. In preferred embodiments, the adapter is housed in a modern version of a spinning top that is powered by repetitive pumping motion using a helical rod and clutch mechanism.

The present disclosure generally provides centrifuge container adapters configured to be used in a centrifuge, e.g., a bench-top centrifuge, and centrifuge systems and methods incorporating the centrifuge container adapters. The centrifuge container adapter may receive a centrifuge container, comprising a sample, the sample, in turn, comprising a fluid. During a centrifuging operation, according to some embodiments, the centrifuge container adapter and centrifuge container may be placed in a rotor cavity in the centrifuge. As a rotor of the centrifuge spins, the fluid may exit the sample within the centrifuge container and be collected in a void space of the centrifuge container adapter. In some embodiments, measurements of the fluid in the centrifuge container adapter may be used to determine characteristics or properties of the sample.

A centrifuge device includes a main body, a driving module, a centrifuge assembly, and a pipe. The main body has an accommodating space and a slot. The slot is connected to the accommodating space. The driving module is at least partially disposed in the accommodating space. The centrifuge assembly is disposed on the main body. A part of the centrifuge assembly is located in the accommodating space and connected to the driving module. The driving module is adapted to drive the centrifuge assembly to rotate. The pipe is connected to the part of the centrifuge assembly and extends out of the main body through the slot.

The invention relates to a rotational unit (10) for a rotor of a dual centrifuge, said rotational unit having a bearing (14) and a rotational head (24) which is connected to the bearing (14), is mounted therein such that it can rotate about an axis of rotation and can be driven relative to the rotor by an additional rotational mechanism of the centrifuge, the rotational head (24) being detachably connected to the receiving unit (40, 80) for conjoint rotation, which receiving unit comprises a sample container receptacle (60, 70, 100, 110) for at least one sample container. The invention is characterized in that the receiving unit (40, 80) and the rotational head (24) are connected by a frictional connection in which some portions of the receiving unit (40, 80) and the rotational head (24) engage in each other in a wedge-like manner, and the frictional connection increases with a movement of the receiving unit (40, 80) along the axis of rotation of the rotational unit (10) in the direction toward the rotational head (24).

A separation container for extracting a portion of a sample for use or testing and method for preparing samples for downstream use or testing are provided. The separation container may include a body defining an internal chamber. The body may define an opening, and the body may be configured to receive the sample within the internal chamber. The separation container may further include a seal disposed across the opening, such that the seal may be configured to seal the opening of the body, and a plunger movably disposed at least partially inside the internal chamber. The plunger may be configured to be actuated to open the seal and express the portion of the sample.

A centrifuge includes a chamber configured to contain a set of one or more samples, an image sensor configured to generate image data, and processing circuitry. The processing circuitry is configured to: initiate centrifugation of the set of samples about a central axis; obtain a set of image data generated by the image sensor during centrifugation of the set of samples; and for each respective sample of the set of samples, apply a machine learning model configured to generate, based on image data representative of the respective sample in the set of image data, a viability score for the respective sample; determine whether the viability score for the respective sample satisfies a viability condition; and output whether the viability score for the respective sample satisfies the viability condition.
