Abstract:
Embodiments are described for receiving first data related to an amount of a first component in a multi-component liquid. A gain may be determined based on the first data. The multi-component liquid may be separated into at least two components. The gain may then be used to control a position of an interface between two separated components of the multi-component liquid, such as by using the gain in changing a speed of a pump pumping at least one of the components.
Abstract:
Described are embodiments for determining components of a composite liquid and controlling the flow of the components into containers. In one embodiment, components of whole blood, after separation, are determined and directed to different containers for collection and storage. Embodiments may be implemented on an apparatus configured to separate multiple discrete volumes of composite liquid (e.g., whole blood) into components.

Abstract:
Die Erfindung betrifft einen Adapter (10) für ein Zentrifugengefäß (30), mit einem einstückigen, schalenartigen Grundkörper, der einen Hohlraum (11) zur Aufnahme des Zentrifugengefäßes (30) begrenzt und einen Bodenbereich (12) und einen an diesen anschließenden Seitenwandbereich (13) aufweist, dessen Oberkante (1 5) den Öffnungsrand des Hohlraums definiert, wobei in dem Seitenwandbereich (13) mindestens eine Dehnungsfuge (14) vorhanden ist, die es erlaubt, durch Anlegen einer Kraft den Seitenwandbereich (13) von einer Ausgangsposition in eine aufgeweitete Position derart aufzuweiten, dass die Länge des Öffnungsrandes in der aufgeweiteten Position verglichen mit der Ausgangsposition vergrößert ist. Der Adapter (10) ist aus einem Kunststoff derart ausgebildet, dass sich der Seitenwandbereich (13) bei Wegfall der Kraft selbsttätig in die Ausgangsposition zurückstellt.
Abstract:
Centrifuges are useful to, among other things, remove red blood cells from whole blood and retain platelets and other factors in a reduced volume of plasma. Platelet rich plasma (PRP) and or platelet poor plasma (PPP) can be obtained rapidly and is ready for immediate injection into the host. Embodiments may include valves, operated manually or automatically, to open ports that discharge the excess red blood cells and the excess plasma into separate receivers while retaining the platelets and other factors in the centrifuge chamber. High speeds used allow simple and small embodiments to be used at the patients side during surgical procedures. The embodiments can also be used for the separation of liquids or slurries in other fields such as, for example, the separation of pigments or lubricants.
Abstract:
A process for the separation of chemical compounds comprises centrifugal partitioning of at least one compound between a mobile liquid phase and an immiscible stationary liquid phase. At least one of the mobile liquid phase and the stationary liquid phase comprises or consists of an ionic liquid. A liquid-liquid chromatography or liquid-liquid extraction apparatus may be used in the process.
