The invention relates to a system, comprising: a) a sample processing unit, comprising an input port and an output port coupled to a rotating container having at least one sample chamber, the sample processing unit configured provide a first processing step to a sample or to rotate the container so as to apply a centrifugal force to a sample deposited in the chamber and separate at least a first component and a second component of the deposited sample; and b) a sample separation unit coupled to the output port of the sample processing unit, the cell separation unit comprising separation column holder (42), a pump (64) and a plurality of valves (1-11) configured to at least partially control fluid flow through a fluid circuitry and a separation column (40) positioned in the holder, the separation column configured to separate labeled and unlabeled components of sample flowed through the column.

A solenoid valve may include a magnetic force generating coil applied with power to generate an electromagnetic force, a valve spool disposed to reciprocate depending on the electromagnetic force generated from the magnetic force generating coil, a holder including a hollow into which the valve spool inserted, the holder forming a plurality of ports to be opened and closed depending on the reciprocating of the valve spool, and a permanent magnet disposed to enclose the hollow of the holder.

A discontinuous wall magnet having an opening or channel is provided. A bead separation magnet having a discontinuous or segmented wall is also provided. The segmented wall causes bead formation to form in a segmented or gapped ring to allow for easier manual pipetting. Also provided are systems and kits having the inventive magnets. Methods of purifying a macromolecule using the inventive magnets are also provided.

A strainer (101) for use in fluid piping. The strainer (101) comprises a body (102) for connection to a fluid piping inflow conduit (201) and to a fluid piping outflow conduit (202). The body (102) defines an interior chamber (103), a fluid inlet port (104) and a fluid outlet port (105). The body (102) defines a fluid flow path (106) between the fluid inlet port (104) and the fluid outlet port (105) that extends through the interior chamber (103). The strainer (101) comprises a screen collector (107) that is removably locatable in the body (102), within the fluid flow path (106). The strainer (101) further comprises a permanent magnet collector (102) that is removably locatable in the body (102). The strainer (101) may be used in fluid circuit piping of a heating or a cooling system.

Methods, systems, and apparatus are provided for automated isolation of selected analytes, to which magnetically-responsive solid supports are bound, from other components of a sample. An apparatus for performing an automated magnetic separation procedure includes a mechanism for effecting linear movement of a magnet between operative and non-operative positions with respect to a receptacle device. A receptacle holding station within which a receptacle device may be temporarily stored prior to moving the receptacle to the apparatus for performing magnetic separation includes magnets for applying a magnetic field to the receptacle device held therein, thereby drawing at least a portion of the magnetically-responsive solid supports out of suspension before the receptacle device is moved to the magnetic separation station. An automated receptacle transport mechanism moves the receptacle devices between the apparatus for performing magnetic separation and the receptacle holding station.

A magnetic drawer separator incorporating at least a first permanent magnet series having a longitudinal, oppositely longitudinal, and outer ends, each permanent magnet having an opening; a longitudinally extending hollow bore within the at least first permanent magnet series, the bore being formed by the permanent magnets' openings; at least a first shaft having longitudinal and oppositely longitudinal ends, the longitudinal end of the at least first shaft engaging the at least first permanent magnet series within the bore; at least a first wiper engaging the outer end of the at least first permanent magnet series; and a frame having longitudinal and oppositely longitudinal ends, wherein the at least first wiper is fixedly attached to the frame's longitudinal end, and wherein the at least first shaft is fixedly attached to the frame's oppositely longitudinal end.

A size sorting device for carbon nanotube agglomerate and a method for separating and collecting dispersed carbon nanotubes using the size sorting device are provided. The size sorting device and method for separation and collection may use a magnetic field for separating and collecting dispersed carbon nanotubes.

The present invention is directed towards an apparatus and methods for a precise, fast and easy to use manipulation of beads. This method is particularly useful to carry out separation between the beads and the remaining supernants present in the fluid, maximizing the collection and purification efficiencies in tips for liquid handling.

Devices and methods are provided for in-line water treatment using strong magnetic fields to influence corrosion, separate toxins, suppress bacteria and bio-fouling, as well as inhibit or greatly reduce mineral scaling due to fluid flow in or around equipment components. For example, a device is provided for applying a magnetic field to a portion of tubing through which a fluid flow, such as water, is conveyed. The device includes a number of links joined together via detachable pivoting connections, such that links may be removed and/or links may be added, thereby allowing a diameter of the device to be adjusted so as to accommodate larger or smaller piping, as necessary, for retrofitting applications. The use of magnetic treatment of fluids such as water may allow extended cycles of operation with higher concentration of mineral salts without the use of chemical scaling suppressants.

A system and a method for separating and recycling magnets made from rare earth elements from an article of manufacture used an alignment device to property position the rare earth magnet for processing. Once proper alignment is made, a separating device removes the magnet and a portion of the article. A heating device demagnetizes the magnets and vibration causes the magnets to separate from the portion of the article. Electromagnets remove the portion of the article and the rare earth magnets pass through for reclamation.
