The invention provides a method, apparatus and system for separating blood and other types of cellular components, and can be combined with holographic optical trapping manipulation or other forms of optical tweezing. One of the exemplary methods includes providing a first flow having a plurality of blood components; providing a second flow; contacting the first flow with the second flow to provide a first separation region; and differentially sedimenting a first blood cellular component of the plurality of blood components into the second flow while concurrently maintaining a second blood cellular component of the plurality of blood components in the first flow. The second flow having the first blood cellular component is then differentially removed from the first flow having the second blood cellular component. Holographic optical traps may also be utilized in conjunction with the various flows to move selected components from one flow to another, as part of or in addition to a separation stage.

The present invention relates to a process for concentrating desired particles comprising a carrier-magnetic-separation comprising the following steps a) providing a feedstock which contains the desired particles and an undesired material; b) adding hydrophobic magnetic particles to the feedstock which results in a loaded feedstock containing agglomerates of the magnetic particles and the desired particles or of the magnetic particles and the undesired material; c) separating the agglomerates from the loaded feedstock by a separation method which results in isolated agglomerates, where the separation method is selected from sorting, electric separation, magnetic separation, screening, classification, gravity concentration, and flotation; d) breaking up the isolated agglomerates to obtain a suspension comprising the magnetic particles in desagglomerated form; and e) separating the magnetic particles from the suspension obtained in step d) by a separation method selected from sorting, electric separation, magnetic separation, screening, classification, gravity concentration, and flotation.

A centrifuge for cleaning a reaction vessel unit, having a rotor for holding at least one reaction vessel unit with its opening(s) directed outwardly, a motor for rotating the rotor around a rotation axis, a housing having a substantially cylindrical inner surface, wherein a drain is provided for discharging fluid expelled from the reaction vessel unit, wherein a gap is provided between the inner surface and the rotor so that by rotating the rotor a wind is generated which drives the expelled fluid on the inner surface to the drain wherein an aspiration pump is connected to the drain for discharging fluid.

Disclosed herein is an improved method for magnetic capture of target molecules (e.g., microbes) in a fluid. Kits and solid substrates for carrying the method described herein are also provided. In some embodiments, the methods, kits, and solid substrates described herein are optimized for separation and/or detection of microbes and microbe-associated molecular pattern (MAMP) (including, e.g., but not limited to, a cell component of microbes, lipopolysaccharides (LPS), and/or endotoxin).

A method and apparatus for continuous magnetic filtration of ferrous mill scale from liquid solution employs a tank for receipt of fluids laden with mill scale. A curvate trough within the tank receives a rotatable magnetic drum and establishes a channel therebetween. An air compressor and associated manifold generate bubbles within the tank and adjacent the rotatable magnetic drum. The mill scale attaches to the bubbles, which are attracted to the surface of the drum where the mill scale accumulates. The accumulation of mill scale particles is moved about the surface of the rotating drum by a scraper proximate the surface thereof. By moving the accumulated mill scale particles to regions of the rotating drum that are of a magnetic force insufficient to retain them upon the surface of the drum, the mill scale particles are removed and passed to a conveyor system.

Embodiments of the present disclosure include separating devices and systems and methods of use. Embodiments of the present disclosure include separation devices including magnetic arrays and sheet-flow separation chambers. In an embodiment, the separating device enables the generation of multiple, and in some configurations, intersecting, high gradient magnetic field lines, resulting in strong separation forces, which permit for scale up to large areas and/or volumes (e.g., extracorporeal blood filtration system).

Provided is a method for processing electronic and electrical device component scrap, which can accurately and efficiently sort electronic and electrical device component scrap. The method for processing electronic and electrical device component scrap includes a separation step of separating non-metal objects 1b or metal objects 1a.sub.1, 1a.sub.2 from electronic and electrical device component scrap 1 containing the metal objects 1a.sub.1, 1a.sub.2 and the non-metal objects 1b using a sorter 10 comprising a metal sensor 2, a color camera 3, an air valve 4, and a conveyor 5, wherein a fixed distance is provided between the metal objects 1a.sub.1, 1a.sub.2 adjacent to each other so as to prevent the non-metal objects 1b between the metal objects 1a.sub.1, 1a.sub.2 from being erroneously detected, when detecting the metal objects 1a.sub.1, 1a.sub.2 in the electronic and electrical device component scrap 1 by the metal sensor 2.

A centrifuge for washing magnetic beads in a reaction vessel unit that includes at least one opening, having a housing including an inner surface and a drain, a rotor disposed within the housing, the rotor being configured to hold a reaction vessel unit with its opening(s) directed outwardly toward the inner surface of the housing, a motor coupled with the rotor to rotate around a horizontal rotation axis, and a magnetic element arranged in the rotor to apply a magnetic field to one or more reaction vessels of a reaction vessel unit held by the rotor.

The present application relates to a concentration process of iron minerals from ultrafine tailings (slimes) from iron ore processing through reverse flotation with pH between 8.5 and 10.5 with the addition of amide-amine type collector, or further a mixture thereof with traditional cationic collectors (amines), in the absence of any depressant, alternatively including a step of high field magnetic concentration, which allows to obtain a concentrate with iron content higher than 66% and contents of SiO2+Al2O3 below 4%.
