    摘要: Generally, the present invention provides a device and method for accurately locating a multi-well plate at a plate-support location, e.g., a work surface, of an automated laboratory machine, such that one or more acting members of the machine, such as an array of pipette tips, optical sensors, or the like, can accurately address and operate on the individual wells. Interior and/or exterior surface regions of one or more wells of a multi-well plate are used as the primary plate features engaged by locating structure of the machine. In one particular embodiment one or more upwardly tapered projections extend from a plate-support surface of a plate-handling machine for mating engagement with the exterior surface regions of one or more wells. In another embodiment, the exterior surface regions along one or more well bottoms are engagingly received within bores, or other receiving structure, formed on the plate-support surface of a machine. In a further embodiment, one or more downwardly extending projections depend from an acting-member support, along with the acting members of a machine. Introduction of the projections into some of the wells of a multi-well plate serves to align the acting members with the plate's other wells. A biasing assembly can be used to press together the engaging surface regions of the wells and the locating structures of the machine.

    摘要: The present invention provides, in one aspect, an apparatus that comprises a disc-shaped substrate defining (1) a central reservoir region, (2) a plurality of channels in fluid communication with, and emanating substantially radially from, the central reservoir region, the channels being coplanar with each other, and each channel having (i) a proximal end which is linked to the reservoir region, and (ii) a distal end, and preferably (3) for each channel, at least one chamber, and preferably three chambers, linked by a passageway in fluid communication with the distal end of that channel. Preferably, each passageway leads from each chamber in a direction that is initially away from the central reservoir region, whereby centrifugation of the substrate about a central axis that is perpendicular to the channels is effective to disperse liquid from the central reservoir region into the channels and chambers, such that any air bubbles in the chambers, channels, and passageways are forced towards the axis of rotation, when such liquid is present in the central reservoir region.

    摘要: The present teachings provide a microfluidic apparatus comprising a body defining at least one channel that extends through said body, the channel including an inlet and an outlet; and an electrode positioned in proximity to the body and configured to provide an electrical field near the outlet of the channel to at least partially confine an eluted sample component passing from the channel. The present teachings also provide an electrophoresis system, comprising a microfluidic chip defining a plurality of channels passing therethrough, each of the channels having an inlet and an outlet; a first electrode in electrical communication with the inlet of each of the channels; a second electrode in electrical communication with the outlet of each of the channels; and a third electrode in electrical communication with the outlet of each of the channels, wherein the third electrode is positioned to provide an electrical field to at least partially confine an eluted sample component passing from any of the channels. The present teachings also provide a method for confining a sample component eluting from a channel of a microfluidic chip, comprising generating an electrical field in proximity to an outlet of a channel in a microfluidic chip to at least partially confine an eluted sample component passing from the channel, thereby reducing distortion of the eluted sample component and mixing with an adjacent eluted sample component.
