Abstract

The reagent package includes a container housing section and a container lid that are sealed together to define one or more inside chambers. The reagent package accommodates a filter screen member and a glass ampoule in the container chamber. The glass ampoule contains one reagent ingredient, usually in a dry powder form and the space within the chamber outside the glass ampoule usually contains a reconstituting liquid ingredient. When the reagent package is ready for use a pressure force is imposed on the outside wall of the chamber adjacent the glass ampoule to crush the ampoule and permit the liquid ingredient within the chamber to mix with the powder ingredient released from the glass ampoule.
