Abstract: A prismatic reflector is provided for incorporation into a centrifugal separation chamber. The prismatic reflector is formed of a light-transmissive material and includes inner and outer walls and first and second end walls. The inner wall is configured to receive light traveling along an initial path and transmit the light to the first end wall, with the first end wall receiving the light transmitted through the inner wall and directing the light toward the second end wall in a direction that is angled with respect to the initial path. The second end wall receives the light from the first end wall and transmits the light out of the prismatic reflector. The initial path of the light may be in a direction toward a rotational axis of the centrifugal separation chamber, with the prismatic reflector redirecting the light into a direction substantially parallel to the rotational axis.

Abstract: The treatment system provides a feature that may reduce cost of the electrochemical plating process by reusing the virgin makeup solution in the spent electrochemical plating bath. The treatment system provides a rotating filter shaft which receives the spent electrochemical plating bath and captures the additives and by-products created by the additives during the electrochemical plating process. To capture the additives and the by-products, the rotating filter shaft includes one or more types of membranes. Materials such as semi-permeable membrane are used to capture the used additives and by-products in the spent electrochemical plating bath. The treatment system may be equipped with an electrochemical sensor to monitor a level of additives in the filtered electrochemical plating bath.

Abstract: A method of obtaining a compound may include adding a substrate to a medium in a reactor, and reacting the substrate in the reactor to form the compound. A first stream is separated from the reaction liquid through a first membrane. A second stream is separated from the reaction liquid through a second membrane. The first membrane is a filtration membrane and the second membrane is configured for liquid-gas or liquid-liquid extraction The first membrane and the second membrane are at least partially immersed in the medium and are moved relative to the reactor during the separation steps.

Abstract: This invention belongs to the field of preparation of macromolecule sample of various volumes, pertaining to a detergent-mixed dry hydrogel particle and a method of using the particle to mass concentrate the macromolecule liquid sample or to enhance specific activity of the protein liquid sample. After thorough suspension and hydration in a detergent solution, the hydrogel particle is separated from the excess of the detergent solution and dried into the detergent-mixed dry hydrogel particle; upon contacting the macromolecule liquid sample in certain ratio with the dry particle having a pore size of its cross-linked network smaller than the macromolecule to allow absorption and swelling of the hydrogel particle, filter centrifugation or filter conical rotating drum centrifugation is exercised to remove the hydrogel particle whose surface is deprived of water and to collect the concentrate filtrate of the macromolecule mass or the protein sample with enhanced specific activity.

Abstract: A membrane separation device is disclosed along with systems and methods employing the device in blood processing procedures. In one embodiment, a spinning membrane separator is provided in which at least two zones or regions are created in the gap between the spinning membrane and the shell, such that mixing of the fluid between the two regions is inhibited by a radial rib or ridge associated with the spinning membrane that decreases the gap between the spinning membrane and the shell to define two fluid regions, the ridge isolating the fluid in the two regions to minimize mixing between the two. Automated systems and methods are disclosed for separating a unit of previously-collected whole blood into selected blood components, such as concentrated red cells and plasma, for collecting red cells and plasma directly from a donor in a single pass, and for cell washing. Data management systems and methods and priming methods are also disclosed.

In an aspect, an alternating tangential flow system for continuous processing may include a feed line containing a fluid. A retentate line may be in fluid communication with the feed line. A first diaphragm may be at an inlet of the retentate line configured to pump fluid toward an outlet of the retentate line. A second diaphragm may be at the outlet of the retentate line configured to pump fluid toward the inlet of the retentate line. A membrane may be in fluid communication with the retentate line between the first diaphragm and the second diaphragm. A retentate pump may be at the retentate outlet configured to pump the fluid out of the retentate line.
