A sample pretreatment tube includes a first tube receiving a primary reagent and a second tube receiving a secondary reagent, wherein the sample pretreatment tube can easily perform sequential reactions by allowing a primary reaction solution to be immediately discharged from the first tube to the second tube by breaking a separation membrane formed at a lower end of the first tube using a pipette, and can limit an insertion depth of the pipette using a stopper formed inside the first tube, thereby preventing damage to the second tube due to the pipette while allowing a space to be formed inside the first tube to facilitate discharge of a primary reaction solution, thus making it possible to immediately perform secondary reaction.

An analysis device employs an analysis kit including a chip provided with a capillary through which a sample flows and a cartridge superimposed on the chip and provided with a liquid reservoir. The analysis device includes a guide-in section into which the analysis kit is guided, a placement section on which the analysis kit placed so as to be supported, a pusher member that pushes the analysis kit from one side face of the analysis kit, contact members that oppose another side face on an opposite side in the horizontal direction to the one side face of the analysis kit placed on the placement section, and contact the other side face of the analysis kit being pushed in by the pusher member so as to position the analysis kit in the horizontal direction, and a measurement member that measures a component present in the sample in the analysis kit.

The present invention provides means with which bile acids, phenols, indoles and organic acids contained in a sample can be stably preserved without cryopreservation of the sample. A sample preservation solution of the present invention is a sample preservation solution used for analyzing at least one component selected from the group consisting of bile acids, phenols, indoles and organic acids contained in a biological or environmental sample, containing at least the following (A) and (B): (A) condensed phosphate or polyoxyethylene sorbitan alkylate; and (B) guanidinium thiocyanate, Tris-HCl (pH 7 to 9), and EDTA.

A pipetting device for processing a fluid sample includes a receiving element and a pipette tip detachably arranged on the receiving element, a displacement element flow-connected to the pipette tip for generating a flow for receiving or ejecting the fluid sample. The pipetting device includes an optically transparent extension detachably arranged on the pipette tip in such a way that the extension is flow-connected to the displacement element via the pipette tip, so that the fluid sample can be received into the extension or can be ejected from the extension by the flow that can be generated by the displacement element.

A disposable diagnostic device includes a body having a first channel and a second channel spaced from the first channel. A shroud is operably fixed to the body and encloses a chamber which is configured in a hermetically sealed-off relation from the first and second channels when the device is in a non-activated first state and is in open communication with at least one of the first and second channels when the device is in an activated second state. A reactant and an inert gas are disposed in the chamber such that the inert gas protects the reactant from being exposed to contaminants when the device is in said non-activated first state. A method of constructing a disposable diagnostic device is also disclosed.

A system for preparing a thrombin serum that can include a containment device, a cage received within the containment device, a cap attachable to the containment device, an inlet port configured to introduce a non-anti-coagulated autologous blood fluid into the containment device, and an outlet port. An activator, such as glass beads, can be present within the containment device.

An analysis device employs an analysis kit including a chip provided with a capillary through which a sample flows and a cartridge superimposed on the chip and provided with a liquid reservoir. The analysis device includes a guide-in section into which the analysis kit is guided, a placement section on which the analysis kit placed so as to be supported, a pusher member that pushes the analysis kit from one side face of the analysis kit, contact members that oppose another side face on an opposite side in the horizontal direction to the one side face of the analysis kit placed on the placement section, and contact the other side face of the analysis kit being pushed in by the pusher member so as to position the analysis kit in the horizontal direction, and a measurement member that measures a component present in the sample in the analysis kit.

Separation of the cellular components of whole blood, or other biological fluid, from plasma or serum can be achieved for assay analysis. A device for facilitating separation can include, for example, a capillary tube that accurately draws target blood volume, a pad that chemically interacts with red-blood cells, such that the red blood cells become chemically and/or physically trapped within pad material, a mechanism for plasma recovery from the pad upon diffusion or active mixing, and a dropper tip that facilitates dispensing the mixture onto a test device. The treatment of the cellular components can be performed prior to contact with a buffer solution, so release of the cellular components into the buffer solution is reduced or prevented. Additional filtration can be provided to filter any remaining cellular components in the mixture.

A sampling kit for tissue including a reaction chamber and a sampling device configured for mounting in the reaction chamber and providing a reaction volume defined between the base of the reaction chamber and the sampling device. The sampling device has a proximal handling portion and a distal scraping portion comprising a scraping formation configured to collect a sample of tissue when the distal scraping portion is rubbed against a surface of the tissue. The sampling device comprises an internal lumen configured for the supply of reaction liquid from a distal end of the tissue sampling device to the reaction volume via a distal aperture disposed in the distal scraping portion when the tissue sampling device is mounted in the reaction chamber. An automated high-throughput sampling and indexing system is also described.

An analysis device that includes a placement section, a pressing member, and a measurement member, has an analysis kit including a chip provided with a capillary through which a sample flows and a cartridge superimposed on the chip, and in which a liquid reservoir placed therein to enable a component present in sample can be measured in a state in which the chip and the cartridge have been fitted together. The analysis kit is placed on the placement section. The pressing member presses the analysis kit in a direction in which the cartridge is superimposed on the chip to sandwich the analysis kit between the pressing member and the placement section, and to fit the chip and the cartridge together. The measurement member that measures the component present in the sample in the analysis kit in which the chip and the cartridge have been fitted together.
