Das Hülsenelement (14) weist an seinem ersten Ende (14.1) eine erste Schubfläche (15.1) zur Aufnahme der Schubkraft (F) des Anschlusselements (11) und an seinem dem Anschlusselement (11) abgewandten Ende (14.2) eine radial innenliegende und dem Dichtelement (13) zugewandte zweite Schubfläche (15.2) zur Weiterleitung der Schubkraft (F) an das Dichtelement (13) auf.
Abstract:
Microfluidic systems and methods are described for capturing magnetic target entities bound to one or more magnetic beads. The systems include a well array device that includes a substrate with a surface that has a plurality of wells arranged in one or more arrays on the surface. A first array of wells is arranged adjacent to a first location on the surface. A second and subsequent arrays, if present, are arranged sequentially on the surface at second and subsequent locations. When a liquid sample is added onto the substrate and caused to flow, the liquid sample will flow across the first array first and then flow across the second and subsequent arrays in sequential order. The wells in the first array each have a size that permits entry of only one target entity into the well and each well in the first array has approximately the same size.
Abstract:
The present invention relates to encapsulated microfluidic packages and methods thereof. In particular embodiments, the package includes a device, a cradle configured to support the device, and a lid having a bonding surface configured to provide a fluidic seal between itself and the device and/or cradle. Other package configurations, as well as methods for making such fluidic seals, are described herein.

Abstract:
The present invention relates to a reaction container that is suitable for conducting PCR. In particular, the invention relates to a pre-loaded reaction container comprising a reagent that is overlaid with a viscous barrier fluid, wherein the viscous barrier fluid seals the reagent from the atmosphere. One or more reaction reagents are added to the pre-loaded reaction container and the container is centrifuged to combine the one or more reaction reagents and the pre-loaded reagent. The pre-loaded reagent is stable at temperatures between 10 and 40°C for many months when immersed within the barrier fluid or is sealed from the atmosphere by the barrier fluid. The present invention also relates to a cap for cooperating engagement with a reaction container, the cap comprising an upper portion for receiving a sample and a lower portion adapted to sealingly engage the inlet aperture of the reaction container to thereby define a reaction chamber between the cap and the reaction container. The upper portion and the lower portion of the cap are in fluid communication by a conduit adapted to substantially retain at least a barrier fluid within the reaction chamber.
