The lid is moveable between a first position wherein the lid is disengaged from the base and a second position wherein the inputs of each channel communicate with corresponding wells in the base. The fluid in each well is drawn into corresponding channels through the inputs thereof by capillary action.

A sample carrier for assaying can include a plurality of pins having a surface that is capable of picking up at least one substance on the surface. The pins can be arranged such that one or more of the plurality of pins are introduced into a corresponding reaction vessel of a microplate. The sample carrier can be divided into a plurality of modules, with each of the plurality of modules comprising one or more pins of the plurality of pins. Methods of use include placing the sample carrier onto a microplate so that at least the one or more of the plurality of pins extend into the corresponding reaction vessel of the microplate.

A storage assembly for two substances to be mixed prior to use, includes a closable dropper tip (3). A first storage chamber (7) is formed by the closable dropper tip (3) and a first container part (2, 4), the first container part (2, 4) being provided with at least one aperture (43). A second storage chamber (8) is formed by a second container part (5) which includes an open end part (52, 53) that closes off the at least one aperture (43) in a first operational position. The first and second container parts (2, 4; 5, 6) are moveable with respect to each other, and are in fluid communication through the at least one aperture (43) in a second operational position wherein the total flow surface area of the at least one aperture (43) is at least equal to a cross sectional area of the first container part.

A specimen collection, storage, transport, and testing device can include an outer vessel containing an internal cup having an openable drain having a brim raised above the bottom floor of the cup. Once opened the drain allows a portion of liquid specimen to flow from the cup into a lower chamber of the vessel containing a number of chromatographic assay strips. A lid sealing the vessel can include a downwardly projecting guide tube having first barrier sealing a bottom aperture. An oblong initiator can axially engage the guide tube, break the first barrier and open the drain to initiate the test while retaining a pool of liquid specimen in the cup for subsequent confirmatory testing.

An apparatus, in particular a microfluid apparatus, includes a chamber for extracting a fluid. The chamber has a wall with an opening. The opening is sealed by a sealing mechanism that is impermeable to specified substances. The apparatus further includes a membrane that contacts the outside of the wall, in a region of an outside of the wall which adjoins the opening, and covers the opening.

The test device is provided with a testing means for testing an added extraction solution utilizing immunochromatography or nucleic acid chromatography, an extraction solution container, and a tubular guiding member having an extraction solution inflow port communicating with the extraction container in a sealed manner at one end side and having an extraction solution outflow port at the other end side. The guiding member is configured so as to have inside the tube a rod-shaped extraction solution guide having capillary action and having one end at the extraction solution outflow port side able to contact the testing means and so that the extraction solution absorbed from the extraction solution inflow port side at the extraction solution guide moves by capillary action through the inside of the extraction solution guide and is added to the testing means through the one end of the extraction solution guide contacting the testing means.

Container assembly including a container for storing a tissue sample and a cover adapted to engage with the container. The cover includes: a top member having a receptacle, a seal for sealing off the receptacle, a puncturing member for breaking the seal by displacement of the puncturing member. The container assembly has a first and a second position, wherein in the first position the container is isolated from the receptacle, and in the second position fluid communication is provided between the receptacle and the container. The container assembly includes a separator positioned between the seal and the bottom of the container, and the separator is provided with at least one aperture adapted to provide a fluid passage between the receptacle and the container.

The present invention related to a reaction vessel and an assay device. A reaction vessel for analysis a sample containing an analyte to be determined, which includes a casing, a first reagent and at least one independent individual element. The casing includes an opening and a detection zone. The opening may be formed on the edge of the casing and used to introduce the sample. The detection zone is disposed at a corner of the casing and used to detect the analyte. The reagent is interacted with the sample. The independent individual element is individually separating from the casing and providing a space and a flow channel for mixing the sample and the first reagent. The sample and the reagent are mixed in the independent individual element so as to determine the analyte in the detection zone, and thereby increasing accuracy of analyte detection.

A microfluidic product pouch assembly may be used in a microfluidic chip. The microfluidic product pouch may include a pouch surrounding an inner chamber and having a rupturing portion and an inner membrane positioned within the inner chamber. The inner membrane may separate the inner chamber into a first cavity and a second cavity. A reagent may be positioned within the first cavity and/or the second cavity. The microfluidic product pouch assembly may also include a rupturing structure. The rupturing structure may be configured to selectively break the rupturing portion of the microfluidic product pouch.

The disclosed embodiments related to an apparatus and methods for biological sample processing enabling isolation and concentration of microbial or pathogenic constituents from the sample. Sample may be obtained directly from a specimen container, such as a vacutainer, and processed directly without risk of user exposure. The disclosed methods and apparatus provide a convenient and inexpensive solution for rapid sample preparation compatible with downstream analysis techniques.
