Abstract: The present invention provides assay devices and methods for detecting the presence of an analyte in a sample. Devices according to the invention include a reagent zone, one or more capture zones and a detection zone. Capture zones can reduce the quantity of labelled conjugate that reaches the detection zone in the presence of a negative marker in the sample and/or in the absence of a positive marker in the sample, facilitating high sensitivity and improved specificity testing.

Abstract: Disclosed is a fluidic assay device for assaying at least one property of a liquid sample, the device comprising: (i) a liquid sample application region; (ii) at least one test flow path in liquid flow communication with the sample application region; (iii) a reference flow path in liquid flow communication with the sample application region; and (iv) a junction region, at which the test flow path and the reference flow path contact one another, the junction region typically comprising an outlet, conduit, chamber or other portion which permits the onward flow of liquid; wherein a liquid flowing along the reference flow path, upon reaching the junction region, has the effect of preventing the flow of liquid along the test flow path. The invention relates to a fluidic device for the passage of a liquid. It also relates to an assay device suitable for measurement of the amount and/or presence of an analyte in, or property of, a fluid sample.

Abstract: A casing assembly suitable for use in a heat exchange assembly comprises a first panel including a first bottom portion, a second panel including a second bottom portion, and a third panel including a third bottom portion. The second bottom portion is interlocked with the first and third bottom portions.

Abstract: A casing assembly suitable for use in a heat exchange assembly includes a first cover, and a second cover adjacent to the first cover. A sealing mechanism positioned between the first and second covers provides a substantially airtight seam between the first and second covers.
