The present disclosure relates to, inter alia, an easy-to-operate, fully closed component, which can be part of an instrument, for purification of biomolecules from biological samples, and subsequent transfer, and testing of the biomolecules, as well as an instrument comprising the component, and a method for using the component.

A reagent container for a tissue processor includes a first body defining a cavity configured to contain reagent; and a second body attached to the first body, wherein the second body defines a reagent passage, a cistern room and an reagent port, the reagent passage is in communication with the cavity, the cistern room is provided between the reagent passage and the reagent port and in communication with the reagent passage and the reagent port; in a flowing direction towards the reagent port, the cistern room has a larger section area than a section area of the reagent passage. The reagent coming out of the reagent passage will significantly slow down in a short time and will not spill out of the reagent container through the reagent port, thereby improving anti-spilling performance of the reagent container during transportation or operation of the reagent container.

A pipette tip made of plastic includes a tubular body having an inner circumference and an outer circumference. The tubular body includes a bottom end defining a bottom opening structured to enable passage of a liquid and a top end defining a top opening that clamps onto a mount of a pipetting device. A seat region for the mount is positioned proximate to the top opening and on the inner circumference of the tubular body. A plurality of flattenings extend in an axial direction on the outer circumference proximate to the top opening. The tubular body defines a contour of an arc polygon in a cross-section through the flattenings on the outer circumference.

The disclosure relates to devices, solutions and methods for collecting and processing samples of bodily fluids containing cells (as well as embodiments for the collection, and processing and/or analysis of other fluids including toxic and/or hazardous substances/fluids). In addition, the disclosure relates generally to function genomic studies and to the isolation and preservation of cells from saliva and other bodily fluids (e.g., urine), for cellular analysis. With respect to devices for collection of bodily fluids, some embodiments include two mating bodies, a cap and a tube (for example), where, in some embodiments, the cap includes a closed interior space for holding a sample preservative solution and mates with the tube to constitute the (closed) sample collection device. Upon mating, the preservation solution flows into the closed interior space to preserve cells in the bodily fluid. The tube is configured to receive a donor sample of bodily fluid (e.g., saliva, urine), which can then be subjected to processing to extract a plurality of cells. The plurality of cells can be further processed to isolate one and/or another cell type therefrom. The plurality of cells, as well as the isolated cell type(s), can be analyzed for functional genomic and epigenetic studies, as well as biomarker discovery.

Described herein in an embodiment is a diagnostic device for detecting the presence of one or more target nucleic acids (e.g., a nucleic acid of a pathogen, such as SARS-CoV-2 or an influenza virus). In some cases, the diagnostic device comprises a substrate comprising both a reagent delivery region comprising one or more reagents (e.g., one or more nucleic acid amplification reagents) and a lateral flow assay region configured to detect one or more target nucleic acids. The substrate may be removably or permanently coupled to an inner component that is movable relative to an outer component. The diagnostic device may further comprise a sample-collecting component coupled to the outer component and/or the inner component. In some embodiments, the inner component may be moved relative to the outer component in order to sequentially expose the substrate to the collected sample. In some cases, the diagnostic device may be used with a reaction tube comprising one or more liquids (e.g., a reaction buffer) and/or a heating unit.

A dissection system has a dissection platform which has a frame, an agitation platform, a tissue section tray, a solution dispenser unit, an airflow drying unit and a waste collection unit and a specimen collector which has a tubular body, a plunger button, a hollow shaft, a piston cylinder, a motor unit, a piston, a piston spring and a piston rod. The agitation platform, the solution dispenser unit, the airflow drying unit and the waste collection unit are disposed on the frame, and the tissue section tray is removably disposed on the agitation platform. The plunger button, the hollow shaft and the piston cylinder are movably inserted in the tubular body. The piston is slidably inserted within the piston cylinder, the piston spring is biased in between the piston cylinder and the motor unit, and the piston rod is connected in between the motor unit and the piston.

A door for a laboratory workstation is disclosed. The laboratory workstation has a horizontally extending work surface for providing a working area. The door is movable in relation to the work surface in a vertical direction perpendicular to the work surface between a safety position, in which the door closes the working area for manual access of a user, an access position in which the working area is open for manual access of a user, and a loading position.

The present disclosure relates to, inter alia, an easy-to-operate, fully closed component, which can be part of an instrument, for purification of biomolecules from biological samples, and subsequent transfer, and testing of the biomolecules, as well as an instrument comprising the component, and a method for using the component.

The present disclosure describes multi-well plates comprising a frame made of a first material having an array of a plurality of holes arranged in a columnar pattern on the top surface and an array of segmented breaking features arranged in a linear columnar pattern which alternates with the columnar pattern of the plurality of holes, and a plurality of tubes/wells made of a second material placed into the plurality of holes, wherein the multi-well plate is manually divisible along the segmented breaking features into one or more columns of multi-well/tube strips. Manually dividing multi-well plate of the disclosure produces multi-well strips or segments that have smooth edges, thereby reducing injuries and glove tear incidences.
