Described herein are various embodiments directed to rotor devices, methods, and systems. Embodiments of rotors disclosed herein may be used to characterize one or more analytes of a fluid. A method may include bonding a first layer and a second layer using two-shot injection molding. The first layer coupled to the second layer may collectively define a set of wells. The first layer may be substantially transparent. The second layer may define a channel. The second layer may be substantially absorbent to infrared radiation. A third layer may be bonded to the second layer using infrared radiation. The third layer may define an opening configured to receive a fluid. The third layer may be substantially transparent. The channel may establish a fluid communication path between the opening and the set of wells.

A pipette tip carrier assembly suitable for storing elongate pipette tips in a biochemical analyser is described. The pipette tip carrier assembly comprises one or more holding elements each adapted to hold, in use, a respective pipette tip oriented such that the elongate dimension of the held pipette tip is parallel to a first axis. The pipette tip carrier assembly also includes a light source arranged to produce, at a position distal to the one or more holding elements along the first axis, light directed towards each of the one or more holding elements so as to be intercepted by one or more pipette tips held in 10 use by the one or more holding elements.

An organizing rack for pooled testing of test samples, as well as a kit for the same, and methods of their use are disclosed. Organizing racks may be used to assist with the creation and testing of specifically organized test sample pools which may be used to minimize the number of tests required to screen a plurality of test samples. Multiple organizing racks may be used in a matrix-based fashion to further reduce the number of tests required to screen a large number of test samples.

A simplified system for air sample collection and analysis for the presence of airborne pathogen is disclosed. An extraction device is used for extracting biomaterial previously deposited on the surface of a capture element of a sampling device, the capture element being of a select cross section and size. The extraction device comprises an upwardly opening head being wider at a top and narrower at a central opening at a bottom. An elongate cavity is attached to the enlarged head at the bottom extending downward from the head and closed at a bottom end to define an interior space, the cavity having a cross section corresponding to the cross section of the capture element and of a slightly larger size than the size of the capture element. An extraction fluid is in the cavity interior space. In use, insertion of the capture element through the head into the elongate cavity extrudes the extraction fluid liquid through the interface between the head and the elongate cavity and provides a fluidic shearing force that serves to solubilize biomaterial from the surface of the capture element.

A specimen holding and positioning apparatus operable to substantially non-movably maintain a specimen (e.g., an excised tissue specimen) in a fixed or stable orientation with respect to the apparatus during imaging operations (e.g., x-ray imaging), transport (e.g., from a surgery room to a pathologist's laboratory), and the like for use in facilitating accurate detection and diagnosis of cancers and/or other abnormalities of the specimen.

The present invention relates to a test system or an assay system (detection system) and test method preferably for use in the Point-of-Care (PoC) field.

A carrier plate, which is used within an electrophoresis process, and to a holding device tailored to the carrier plate, the carrier plate having a region with a magnetic property and a positioning device. The magnetic property is designed to fix the carrier plate in the laboratory device. The positioning device is designed to guarantee a position of the carrier plate in the laboratory device.

According to one embodiment, a nucleic acid reaction tool includes a support having a first surface, a covering body having a second surface, and a groove opened on the second surface, and a primer set. The covering body is in contact with the support to form a reaction space surrounded by the first surface and the groove. The groove includes, on an inner surface of the reaction space, rising surfaces opposed to each other, and a rear surface connecting one end of the side surfaces, and a primer fixing region to which the primer set is fixed, the primer fixing region being located at a corner where the one end of the side surfaces connected to the rear surface in the reaction space.

A holder (40) for holding a stack (10) of coverslips (11) or specimen slides (11) has a bottom (20) having at least one side wall (21a, 21b, 22a, 22b) connected thereto, wherein an inner side of the bottom (20) is embodied for placement of the stack (10) of coverslips (11) or specimen slides (11) and carrying that stack (10), and an outer side of the bottom (20) and/or an outer side of the at least one side wall is configured to receive an identification label, such as an RFID (30), and the holder includes such the identification label, such as an RFID (30).

A heater for a microfluidic test card is disclosed herein. In a general example embodiment, a test card for analyzing a fluid sample includes at least one substrate layer including a microchannel extending through at least a portion of one of the substrate layers, and a printed substrate layer that is bonded to or printed on one substrate layer of the at least one substrate layer. The printed substrate layer includes a heater printed on the printed substrate layer so as to align with at least a portion of the microchannel. The heater includes two electrodes aligned on opposite sides of the microchannel, and a plurality of heater bars electrically connecting the two electrodes. The plurality of heater bars includes a central heater bar disposed between outer heater bars.
