ABSTRACT:
A sample testing system may include a vessel comprising at least two flexible compartments and a self-sealing injection channel. The injection channel may be capable of (a) being in fluid communication with at least one of the flexible compartments, and (b) being pierced by a needle in fluid communication with a reagent reservoir. The system may further include a housing, a cavity in the housing, so sized and shaped to receive the vessel, at least one contact member, and a sensor to sense a condition of a fluid sample in the vessel and to generate an output signal indicative of that condition. The contact member may be so positioned as to be engageable with one of the flexible compartments when the vessel is in the cavity and as to compress the engaged flexible compartment, thereby driving fluid flow from the engaged flexible compartment to the other of the at least two compartments of the vessel. The vessel may include a wall constructed of a flexible material permitting substantial compression of the vessel.
