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 vessel may comprise a tubule having an opening for receiving a sample material and at least one compressible section, a generally rigid container receiving at least a portion of the tubule; and an interface in fluid communication with the opening in the tubule. The at least one compressible section may have a wall constructed at least partially from a material having sufficient flexibility to permit compression of opposed sections of the wall into contact. The interface may facilitate delivery of a sample material to the tubule through the opening. A sample vessel may also comprise a tubule having a plurality of lumens and a wall constructed at least partially from a material having sufficient flexibility to permit compression of opposed sections of the wall into contact with one another and a pressure gate connecting at least two lumens to permit selective fluid flow between the at least two lumens.
