摘要:
Embodiments of the present invention include a specimen enclosure apparatus . The specimen enclosure apparatus includes a container having a cavity configured to receive the specimen and an opening extending through a neck of the container to the cavity. An internal flange is positioned intermediate the neck (406) of the container. The specimen enclosure apparatus further includes a closure device (200a) configured to be received in the opening. The closure device has a flange seal portion configured to contact the internal flange to form a flange seal proximate the cavity and further has a radial travel limiter integrally formed with the closure device that is configured to contact the container in the opening to limit radial movement of the flange seal portion relative to the internal flange. Containers and closure devices are also provided.
摘要:
An instrument for conducting nucleic acid amplification reactions in a disposable test device. The test device includes a first reaction chamber containing a first nucleic acid amplification reagent (e.g., primers and nucleotides) and a second reaction chamber either containing, or in fluid communication, with a second nucleic acid amplification reagent (e.g., an amplification enzyme such as RT). The instrument includes a support structure receiving the test device. A temperature control system maintains the first reaction chamber at a first elevated temperature but simultaneously maintains the second nucleic acid amplification reagent at a second temperature lower than the first temperature so as to preserve the second nucleic acid amplification reagent. An actuator operates on a fluid conduit in the test device to place the first and second reaction chambers in fluid communication with each other after a reaction has occurred in the first reaction chamber at the first temperature. A pneumatic system is also provided that assists in fluid transfer of a reaction solution from the first chamber to the second chamber.
摘要:
The present invention is directed to sample test cards having an increased sample well capacity for analyzing biological or other test samples. In one embodiment, the sample test cards of the present invention comprise one or more fluid over-flow reservoirs, wherein the over-flow reservoirs are operatively connected to a distribution channel by a fluid over-flow channel. In another embodiment, the sample test cards may comprise a plurality of flow reservoirs operable to trap air thereby reducing and/or preventing well-to-well contamination. The test card of this invention may comprise from 80 to 140 individual sample wells, for example, in a test card sample test cards of the present invention have a generally rectangular shape sample test card having dimensions of from about 90 to about 95 mm in width, from about 55 to about 60 mm in height and from about 4 to about 5 mm in thickness.
摘要:
A unit dose test device for a nucleic acid amplification reaction has the form of an elongate disposable test strip. The test strip includes a dual-chamber reaction vessel preloaded with nucleic acid amplication reaction agents, a plurality of wells for processing a reaction occuring in the reaction vessel, and a hinge cover above a membrane, sealing both reaction chambers. A desiccant is loaded in proximity to and in communication with first or second reaction chamber.

摘要:
A holding structure for holding a plurality of culture plates (12) in a stacked arrangement includes a feature (44) for de-nesting the bottom culture plate from the plate above it. The de-nesting feature is preferably a structure which urges a plate to move laterally relative to the plate above it. The de-nesting of the bottom culture plate from the adjacent culture plate facilitates withdrawal of the bottom culture plate from the base via a robotic plate transfer mechanism. The de-nesting feature can be entirely passive, such as ramps formed in the base of the holding structure.
