Abstract
A gas flow cartridge includes a tube-like member which defines a reaction chamber in which a pool of liquid is subjected to an analytical test. A coating of debubbling agent is applied to an area of the tube-like member above the reaction chamber. The debubbling agent collapses bubbles of noncoagulated fluid but allows bubbles of coagulated fluid to continue an upward movement above the area where the coating is applied. Coagulation is detected by sensing the coagulated bubbles moving upward in the tube-like member. A quantity of activator agent is initially confined with the reaction chamber, preferably within a structure defined by a segment of paper-like material formed into an activator retaining form. The paper-like material unrolls or unfolds during the analytical test.
