Abstract:

A sample processing tubule may include a first segment, a second segment, and a third segment. Each segment may be defined by the tubule, may be fluidly isolated, at least in part by a breakable seal, may be so expandable as to receive a volume of fluid expelled from another segment, and may be so compressible as to contain substantially no fluid when so compressed. Each segment may contain at least one reagent.

Abstract:

A sample processing cartridge may include a plurality of segments arranged in an array at least two rows long and two columns wide. Each segment may be defined by at least one wall of the sample cartridge, fluidly isolated from adjacent segments at least in part by at least one breakable seal or by at least one permanent seal, so expandable as to receive a volume of fluid expelled from another segment, and so compressible as to contain substantially no fluid when so compressed. At least two adjacent segments of at least one row of the array may be aligned along a longitudinal axis of the row and have substantially the same height along a latitudinal axis of the row. At least two adjacent segments in at least one row may be separated by a permanent seal to form at least two tracks. At least one segment, or at least two adjacent segments separated by a breakable seal, may be in fluid communication with the at least two tracks. At least one segment may contain at least one reagent.

Abstract:

A sample processing vessel may include a branch segment and at least two tracks. The at least two tracks may be fluidly isolated from one another by a permanent seal. The tracks may be segmented by breakable seals. The branch segment may be temporarily isolated from the tracks by breakable seal(s) and put in fluid communication with the tracks once those seal(s) are broken, such that fluid received by the branch segment is divided into portions that pass into both tracks.
