  • Patent number: 10953409
    Abstract: A centrifugal separator includes a casing which delimits a space which is sealed off from and having an under pressure in relation to the surroundings, by at least one seal. A rotor is arranged for rotation around a rotational axis and forms within itself a separation space. In the separation space, centrifugal separation of at least one higher density component and at least one lower density component from a fluid takes place during operation. At least one inlet extends into the rotor for introducing the fluid to the separation space. At least one first outlet extends from the rotor for discharge of at least one component separated from the fluid during operation. The rotor includes at least one second outlet extending from a portion of the separation space to the space for discharge of at least one higher density component separated from the fluid during operation.

  • Patent number: 10919050
    Abstract: Accurate measurement of acceleration caused by imbalance in the balance of a rotor is realized even in high-speed rotation with an acceleration sensor which has a processing speed required in low-speed rotation and a control unit. A centrifuge according to the present invention includes a rotor, a drive source for rotating the rotor, a rotating shaft for coupling the rotor and the drive source, an acceleration sensor, and a control unit. The acceleration sensor outputs values indicating acceleration in two different directions which are perpendicular to an axial direction of the rotating shaft. The control unit obtains an acceleration corresponding value, which is a value corresponding to acceleration in a direction perpendicular to the axial direction of the rotating shaft, based on values indicating acceleration in the two different directions and stops rotation of the rotor in a case where the acceleration corresponding value satisfies a determination criteria.

  • Patent number: 10919049
    Abstract: Mid-procedure termination of a mononuclear cell collection procedure may prevent collection of an amount of red blood cells that is required to harvest a complete mononuclear cell product. Blood separation systems and methods are provided for minimizing the impact of or recovering from mid-procedure termination of such a mononuclear cell collection procedure. According to one approach, blood or separated red blood cells are conveyed into a red blood cell collection container relatively early in the procedure to minimize the impact of a later termination of the procedure. According to another approach, blood and/or separated red blood cells within a fluid processing assembly are redirected through the fluid processing assembly following mid-procedure termination to allow for at least partial mononuclear cell collection.

  • Patent number: 10814338
    Abstract: The botanical extraction and purification device described in this patent provide the ability to extract and purify botanical compounds from a diverse plant species through specially crafted process sequences that effectively reach the desired botanical component despite differences in botanical material types and unique differences in organic chemical characteristics. The technological package consists of two main processing centers; each is a combination of process features that can be personalized to effectively address unique extraction requirements. When combined, the extraction processes deliver capabilities in product throughput speed and product purity not available using previously available separation methods. The first component of this package is a CUP that transfers chemical compounds from botanical material into a solvent. The second component is an AISP. This device separates unwanted botanical compounds from the solvent, resulting in a relatively pure plant extract.

  • Patent number: 10807094
    Abstract: A device and method are provided to facilitate the handling of a volume or fluid. The device includes an elongated tube having an open first end and a second end. The tube defines a reservoir for receiving the volume or fluid. A stanchion has a first end received within the reservoir of the tube and a second end projecting from the open end of the elongated tube. In operation, the elongated tube is deposited in a first capsule having fluid therein. The first capsule is centrifuged such that the volume of fluid is received in a reservoir in the tube through the open end. The tube is removed from the first capsule and positioned in a second capsule such that the open end of the tube is spaced from a closed end of the second capsule. The second capsule is centrifuged such that the volume of fluid is expelled from the reservoir of the tube.
