The present invention generally relates to a sample receiving device for releasably storing a substance. The sample receiving device includes a lid having a reservoir for retaining the substance, and a pierceable barrier sealing the substance within the reservoir; and b) a funnel for receiving a sample and configured for closure by the lid. The funnel is configured for releasable attachment to a sample receptacle such that a sample can be provided to the funnel and travel through the channel in the funnel into the sample receptacle. Further, the funnel includes one or more cutting ribs for cutting the pierceable barrier such that upon cutting of the pierceable barrier the substance is released from the reservoir, flows through the channel in the funnel and into the sample receptacle to be mixed with the sample. The present invention also provides a kit for collecting and storing biomolecules.

There is provided an automated system for preparing tissue samples that comprises one or more microtomes, a hydration system, and a processor, the processor being programmed to initiate facing, by one or more microtomes, of a first tissue block comprising a first tissue sample embedded in an embedding material, and cause the first tissue block to be hydrated by the hydration system for a first predetermined time, and initiate facing, by one or more microtomes, of a second tissue block while the first tissue block is being hydrated, the second tissue block comprising a second tissue sample embedded in an embedding material, and cause the second tissue block to be hydrated by the hydration system for a second predetermined time, and to initiate the one or more microtomes to begin sectioning of the first tissue block while the second tissue block is being hydrated.

A histologic tissue sample support device includes a tissue cassette, a frame, and a lid. The tissue cassette has a recess including a body with at least one side wall and a bottom wall and is formed of material that can be successfully sectioned in a microtome and is resistant to degradation from solvents and chemicals used to fix, process and stain tissue. The tissue cassette is movably coupled to the frame by a frame-cassette connector. The lid is coupled to a peripheral portion of the frame by a lid-frame connector. The lid and the tissue cassette are capable of moving from a first position to a second position with respect to the frame, and in the second position the bottom wall and at least a portion of the side wall extend beyond a bottom edge of the frame for sectioning in a microtome.

The present invention discloses an electrophoretic chip comprising: (a) a non-conductive substrate designed to support elements of said electrophoretic chip; (b) an electrode structure for conducting current through said electrophoretic chip, printed on said non-conductive substrate and comprising a counter electrode and at least one working electrode, each electrode comprising a conductive low-resistance ink layer printed on the non-conductive substrate, and a carbon ink layer printed on top of and fully or partially covering said conductive low-resistance ink layer; (c) a dielectric ink insulator layer placed on top of, and covering, said electrode structure, said dielectric ink insulator layer having at least one opening above the counter electrode and at least one opening above said at least one working electrode, thereby forming at least one addressable location; and (d) a molecule capturing matrix spotted on and covering said at least one addressable location, thereby creating at least one microgel region.

A magnetic bead separation method includes: storing, in a container, a mixed liquid containing a magnetic bead and a liquid containing target molecules, and adsorbing the target molecules on the magnetic bead, the magnetic bead containing a Fe-based metal soft magnetic particle and a coating film with which the Fe-based metal soft magnetic particle is coated, and having a saturation magnetization of 50 emu/g or more and 250 emu/g or less; applying an external magnetic field to the container and magnetically attracting at least a part of the magnetic bead by the external magnetic field; and applying an acceleration to the container while the magnetic bead is magnetically attracted by the external magnetic field and desorbing the liquid adhering to the magnetic bead.

In one configuration, a handheld compound tester to process and detect presence of a compound in a tablet is disclosed. The handheld compound tester may include a sampling chamber configured to receive a tablet and a lid couplable with the sampling chamber. The coupling of the lid with the sampling chamber may cause cutting of the tablet. A liquid may be added inside the sampling chamber to create a mixture with segments of the tablet. The mixture may be then received by a housing adjoining the sampling chamber. A test strip disposed within the housing, upon contacting the mixture, may be configured to indicate a presence of the compound in the mixture.

A flow assay cartridge for housing and protecting a flow assay membrane or lateral flow test strip which can be vertically stacked and is adapted for high-throughput automated lateral flow assay testing and analysis. The flow assay cartridge comprises a base and lid for receiving the flow assay membrane, and top and bottom engagement features such that two or more flow assay cartridges can be releasably adjoined in a vertical orientation such that they can be easily handled by an automated assay apparatus.

A diagnostic sample tube, comprising a tube body having a tube cavity to receive a test sample; and a tube body lid; the tube body and the tube body lid are formed as a single piece; a mechanical fastening mechanism formed with the single piece, the mechanical fastening mechanism comprising an engagement protrusion and an engagement protrusion receiver; wherein, when the mechanical fastening mechanism is fastened, the mechanical fastening mechanism holds the tube body and the tube body lid in a closed position relative to one another with the cavity closed; and wherein, when the mechanical fastening mechanism is fastened, the engagement protrusion receiver surrounds a longitudinal length of the engagement protrusion.

This invention relates to an apparatus for conducting immunoassay test. The apparatus includes a groove unit having a groove along a vertical direction configured to hold a rod-shaped portion of a probe along the vertical direction, and a push pin configured to move along a horizontal direction, the push pin being capable of residing at a first position and a second position. A tip of the push pin is capable of pressing the rod-shaped portion of the probe against the groove when the push pin resides at the first position. The distance between the tip of the push pin and the groove is larger than a diameter of the rod-shaped portion of the probe when the push pin resides at the second position.
