1. A sample testing system, comprising:

  • a housing;

    a cavity in the housing, so sized and shaped to receive a chamber;

    a first contact member, so positioned;

    as to be engageable with a first flexible segment of the chamber when the chamber is in the cavity; and

    as to compress the first flexible segment, thereby driving fluid flow from the first flexible segment through a central segment of the chamber to a second flexible segment of the chamber;

    a second contact member so positioned;

    as to be engageable with the second flexible segment of the chamber when the chamber is in the cavity; and

    as to compress the second flexible segment, thereby driving fluid flow from the second flexible segment through the central segment to the first flexible segment; and

    a sensor to sense a condition of a fluid sample in the chamber and to generate an output signal indicative of that condition.
