Provided herein are cap and tube component embodiments that permit ergonomic engagement and disengagement. Also provided herein are assemblies thereof in which a cap is in sealing engagement with a tube. When engaged with a tube, a cap may be pivoted with respect to a point located on the interior rim of the tube opening by applying a relatively small force to the exterior surface of the cap. Pivoting the cap at this point on the tube can break the seal between the tube and cap and permit removal of the cap from the tube for manipulation of fluid in the tube.

The present disclosure provides a substantially sealed system and methods of use thereof for nucleic acid amplification. Said system includes, for example a base, a nucleic acid amplification reaction vessel, a collection cap, a storage cap and/or a housing. The system reduces contamination before, during and after the amplification reaction. Therefore said system reduces amplification of spurious nucleic acids or amplification products. The present disclosure also provides methods of amplifying nucleic acids using said system.

A histologic tissue sample support device (200) includes a tissue cassette (112), a frame (14), and a lid (118"). The tissue cassette (112) has a recess (112b) including a body (112a) with at least one side wall and a bottom wall (112c) 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 (112) is movably coupled to the frame (14). The lid (118") is separably coupled to a peripheral portion (16) of the frame (14). When the lid (118") is separated from the peripheral portion (16), the lid (118") and the tissue cassette (112) are capable of moving from a first position to a second position with respect to the frame (14), and in the second position the bottom wall (112c) and at least a portion of the side wall extend beyond a bottom edge of the frame (14) for sectioning in the microtome.

Die vorliegende Erfindung betrifft ein druckdichtes Vorratsgefäß enthaltend eine Flüssigkeit, wobei das Vorratsgefäß einen Innenboden und eine Oberseite aufweist und mit einem Verschluss druckabschließend verschlossen ist, und wobei die Beschaffenheit des Vorratsgefäßes das druckabschließende Einstechen von wenigstens zwei Hohlnadeln gestattet; ein Verfahren zum Überführen einer Flüssigkeit aus einem Vorratsgefäß in ein Reaktionsgefäß, umfassend die Schritte Bereitstellen des erfindungsgemäßen Vorratsgefäßes, druckabschließendes Einstechen einer ersten Hohlnadel, die mit einem Spülflüssigkeitsreservoir verbunden ist, und druckabschließendes Einstechen einer zweiten Hohlnadel, die mit dem Reaktionsgefäß verbunden ist, Einleiten von Spülflüssigkeit über die erste Hohlnadel aus dem Spülflüssigkeitsreservoir in das Vorratsgefäß unter Austreiben der Flüssigkeit über die zweite Hohlnadel aus dem Vorratsgefäß in das Reaktionsgefäß; sowie eine zur Durchführung des erfindungsgemäßen Verfahrens geeignete Vorrichtung.
摘要:
A sampling and assay kit comprises a cuvette for holding a quantity of a buffer solution and a sample holder including a capillary tube for obtaining a sample. The sample holder includes a body portion which holds the capillary tube. The body portion when inserted in the cuvette, is effective to position the capillary tube within the cuvette at a predetermined position above the end of the cuvette.
