Devices and methods for preparing and delivering biological assay samples are provided
herein. Components of such devices include a sample receiving module within which a
biological assay sample can be prepared and a cap, which when operatively coupled with
the sample receiving module, pressurizes the module. These devices can be employed for
subsequently delivering a biological assay sample.

[0002] Biological assays sometimes require one or more fluids to be mixed, moved,
separated and/or otherwise processed. Some biological assay devices and methods employ
passive media control techniques such as capillary action for moving such fluids. Other
methods and devices use active media control techniques which include propel ling one or
more fluids into, through and/or out of devices. Active media control techniques, in some
instances, involve employing one or more pumps, such as electrically driven pumps, to …
