Tube and float systems for separation and axial expansion of the buffy coat are provided. Generally, the systems include a flexible sample tube and a rigid separator float having a specific gravity intermediate that of red blood cells and plasma. The sample tube has an elongated sidewall having a first cross-sectional inner diameter. The float has a main body portion and one or more support members protruding from the main body portion to engage and support the sidewall of the sample tube. During centrifugation, the centrifugal force enlarges the diameter of the tube to permit density-based axial movement of the float in the tube. After centrifugation is ended, the tube sidewall returns to its first diameter, thereby capturing the float and trapping the buffy coat constituents in an annular volume. Several different systems for capturing and retrieving the buffy coat constituents are described. 1271-. (canceled)272.

A device for insertion into a rotor of a centrifuge has at least two bodies stacked one above the other in a stacking direction inside a housing. The housing is configured such that it can be inserted into a holder of the rotor of the centrifuge. With a correct reception of the device in the centrifuge, and upon a rotation of the rotor, a spacing of one of the at least two bodies in relation to the axis of rotation of the rotor is smaller than a spacing of another of the at least two bodies in relation to the axis of rotation of the rotor. A first of the at least two bodies has at least one first cavity and a second cavity and a second body of the at least two bodies has at least one first cavity. The two bodies are movably disposed in relation to each other inside the housing in order to fluidically couple, in a first phase, responding to a rotation of the rotor, the first cavity of the first body to the first cavity of the second body and to fluidically couple in a second phase the second cavity of the first body to the first cavity of the second body.

Systems and methods for separation and analysis of target analytes

Номер: US20130280146A1
Автор: Jonathan E. LUNDT, Joshua J. NORDBERG, Ronald C. Seubert
Принадлежит: Rarecyte Inc

Systems for analyzing multiple target analytes of a suspension include a tube and multiple floats. The target analytes are conjugated with at least one fluorescent marker, and the tube, multiple floats and suspension are centrifuged so that at least a portion of each target analyte is located between the inner wall of the tube and the surface of the respective float. In order to identify each target analyte, the portions of the suspension between the tube and each float is illuminated with one or more channels of excitation light, which causes the at least one fluorescent marker to become excited and emit light at longer wavelengths. One of the target analytes may be used to assess quality control or may aid in a subsequent analysis or diagnosis.

A centrifugal filtering device includes a centrifugal drum and a rotary filter. The centrifugal drum has a receiving space for accommodating the source fluid. The rotary filter rotatably mounted in the receiving space includes a filter body and a filtrate discharge pipe. The filter body includes a filter cartridge defining a filtrate-collecting space. The filtrate discharge pipe connecting the filter body is communicative in space with the filtrate-collecting space. By rotating at least one of the centrifugal drum and the rotary filter, the source fluid is driven to generate a vortex by a centrifugal force. The centrifugal force drives the source fluid to form a heavy-phase fluid hitting the centrifugal drum and a light-phase fluid approaching the filter cartridge. The light-phase fluid passes the filter cartridge and then reaches the filtrate-collecting space as a filtrate, and the filtrate is exhausted via the filtrate discharge pipe of the centrifugal filtering device.

An exchangeable separation insert for a centrifugal separator includes a rotor casing enclosing a separation space in which a stack of separation discs is arranged, and first and second stationary portions. A feed inlet supplies a fluid mixture to the separation space. The insert includes a light phase outlet and a heavy phase outlet. The feed inlet is arranged at a first axial end of the rotor casing. One of the light phase outlet and heavy phase outlet is arranged at a second axial end. A first rotatable seal seals and connects the feed inlet and a second rotatable seal seals and connects one of the light phase outlet and heavy phase outlet. 1. An exchangeable separation insert for a centrifugal separator comprising:a rotor casing enclosing a separation space in which a stack of separation discs is arranged, the rotor casing being arranged to rotate around an axis of rotation;a first stationary portion and a second stationary portion, said rotor casing being axially arranged between said first and said second stationary portions;a feed inlet for supply of a fluid mixture to be separated to said separation space;{'b': '2', 'a light phase outlet for discharge of a separated phase of a first density, and a heavy phase outlet for discharge of a separated phase of a second density higher than said first density, wherein said feed inlet is arranged at a first axial end of said rotor casing (), and wherein one of said light phase outlet and heavy phase outlet is arranged at a second axial end, opposite the first axial end, of the rotor casing;'}a first rotatable seal for sealing and connecting said feed inlet to a stationary inlet conduit in said first stationary portion; anda second rotatable seal for sealing and connecting one of said light phase outlet and heavy phase outlet to a stationary outlet conduit in said second stationary portion.2. The exchangeable separation insert according to claim 1 , wherein said light phase outlet is arranged at the first axial end and ...

A self-emptying separator includes a rotatable drum with an inlet, a liquid outlet, outlet openings for solid material, and a control system. A flowable starting product is cleared of the solids in continuous operation in a centrifugal field in the rotating drum. A continuous discharge of a clear phase is performed. A solid phase is discharged via the outlet openings from a solids collecting space of the drum into an annular solids catcher. The solids catcher has a device for generating a fluid curtain against which the solids, issuing from the outlet openings for solid material, impact. 113-. (canceled)14. A self-emptying separator , comprising:a rotatable drum having a vertical axis of rotation;a feed;at least one liquid drain;outlet openings for solids; anda controller,wherein a free-flowing starting product is clarified of the solids in continuous operation in a centrifugal field in the rotatable drum,wherein a clear phase is emptied continuously and a solid phase is emptied from a solid collection chamber of the rotatable drum into a ring-shaped solid collector continuously or discontinuously via the outlet openings,wherein the solid collector comprises a device for producing a fluid curtain, on which the solid phase exiting from the outlet openings for solid impact, wherein the device for producing a fluid curtain comprises openings that are distributed on an upper wall of the ring-shaped solid collector or on an adjoining component, the openings of the device for producing a fluid curtain have exit ends that are axially oriented downward.15. The self-emptying separator of claim 14 , wherein the openings of the device for producing a fluid curtain are nozzles.16. The self-emptying separator of claim 15 , wherein the nozzles are distributed on a circumference of the solid collector.17. The self-emptying separator of claim 16 , wherein at least four or more nozzles are distributed on the circumference of the solid collector.18. The self-emptying separator of ...
