Abstract: A fluid diverting module includes a multi-position fluid diverting device comprising three-dimensional movable flow-paths with minimal tortuosity in the movable portion (the rotor) of the fluid diverting device. In some embodiments, the device is also equipped with a filtration module that is capable of filtering solid particulates from fluidic samples. The invention relates to an area of non-disruptive sampling from various sample sources including ones containing solids. The fluid diverting device maintains fluid communication between the sample source and a pressure creating device in all positions of the fluid diverting device, thus conserving the pressure inside the sample source during sampling. The sampling operation is controlled from a controller, which is equipped with a software for manual or intelligent control.

Abstract: Sample preparation device for receiving in sealing relation one or more filter assemblies and one or more sample containers, each container uniquely positioned within the device to receive filtered sample from a designated filter. The device includes a body, a lid disposed on the body, a container tray, a base, an integrated seal on the body, a valve and a valve actuator. The tray can be disposed in a vacuum chamber defined by the lid and the body, and one or more sample containers can be disposed in the tray. When properly positioned in the tray in the vacuum chamber, each container is in fluid communication with a single respective filter assembly disposed in sealing relation in a respective aperture in the lid. A single actuation of a valve causes the lid to seal to the base and drives the simultaneous filtration of a plurality of samples.

Abstract: Apparatuses for preparing a sample are disclosed herein. The apparatuses include a chamber, a first valve at least partially disposed in the first chamber, a second valve at least partially disposed in the first chamber, and a pump comprising an actuator and nozzle.

Abstract: Embodiments of the present invention feature a device (1) and method for performing steps of a multi-step process in parallel. The device (1) and method feature a rotor assembly (13) having vessel stations (33) and stator assembly (15) having work positions. The rotor assembly (13) rotates the vessels (17) to the work stations to perform steps of a multi-step process at the same time.

Abstract: A thin film bio valve device and an apparatus for controlling the thin film bio valve device are effectively applied in a valve structure of a thin film device, such as a lab-on-a-chip, a protein chip, or a DNA chip, for diagnosing and/or detecting a small amount of material in a fluid.

Abstract: A micro fluidic device includes a valve/pump-unit with reduced dead volume having a substrate. The lower surface of the substrate includes two micro channels spaced apart by a valve area of the substrate that separates the two micro channels. A flexible membrane is arranged on the lower surface of the substrate facing an actuating element located in a through going cut-out of a cover element. Movement of the actuating element towards and away from the valve area of the substrate causes a pump and/or valve action of the flexible membrane area, respectively, to cause or stop a directed fluid flow between the two micro channels through a channel formed between the valve area of the substrate and the flexible membrane.

Abstract: Devices, instruments, systems and methods are provided in which a primary line that receives a biological fluid is selectively sampled by a plurality of collection chambers. Selective sampling occurs by selectively accessing the primary line and selective engagement of a sampling pump under control of a microprocessor. Further, the instrument housing reversibly houses a drive assembly and sample collection housing to permit the interchangeability of drive assemblies and collection housings and thus enhance sterility or reduction of cost.

Abstract: A cassette for preparing a sample is disclosed herein. The cassette includes a housing, which encloses the structures and the processes used to prepare the sample.

Abstract: A microfluidic valve device includes a microfluidic chip including a substrate having a channel, a valve disposed within the channel and configured to change a conductance of the channel, with the valve having an inner channel formed therein, and an oscillator configured to generate a traveling wave. The valve is moved by generating the traveling wave to open and close the channel.

Abstract: An anticoagulant-coated dipstick is selectively receivable by the central fill port of a rotor of a blood centrifuge. The dipstick includes an elongated, rod-like member having a first axial end and an opposite second axial end, and a cap affixed to the second axial end. At least a portion of a surface of the rod-like member is coated with an anticoagulant. The elongated rod-like member of the dipstick is dimensioned in length and diameter to be receivable through the central fill port of the rotor to contact a blood sample contained therein. The cap is circular in shape, with a diameter that is greater than that of the rotor fill port to entirely cover and seal the fill port to prevent leakage therethrough of a blood sample contained in the rotor, especially when the rotor is gently agitated or inverted.

Abstract: A microfluidic system based on centrifugal force and a bio cartridge for the microfluidic system are provided. The system includes a spindle motor, a rotatable frame detachably mounted on the motor and having a plurality of cells separated by partition walls, and the bio cartridge detachably accommodated in one of the plurality of cells. The bio cartridge includes a chamber for storing a fluid, a channel for transporting the fluid, and a valve for controlling the flow of the fluid. The valve may include a phase transition material, and exothermic minute particles dispersed in the material and generating heat when energy is applied thereto.
