The reagent package includes a container housing section and a container lid that arc sealed together to define one or more inside chambers. An opening in the container lid provides access to a corresponding chamber. The chamber opening is controlled by a valve that is pivotable from an open position to a closed position and vice versa. When the valve is in an open position the container chamber can be accessed through the valve with an aspiration probe and a dispensation probe. The reagent package accommodates a filter screen member and a glass ampoule in the container chamber. The glass ampoule contains one reagent ingredient, which can be a dry powder and the space within the chamber outside the glass ampoule can contain a reconstituting liquid. 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 within the chamber to mix with the dry powder released from the glass ampoule. Drainage channels can be provided in the floor of the container to direct the flow of liquid at the container floor into a filter well. Micro-slits are provided in the wall of the filter …
