The reagent package includes a container housing section and a container lid that are sealed together to define one or more inside chambers. Anopening 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 reagentingredient, 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 thechamber to mix with the dry power released from the glass ampoule. The reagent package can be formed as a dual package with separate non-communicable chambers that each contain different reagents. In one embodiment of the invention a locking clip member is secured to the reagent package to enhance the seal provided by the valves when the valves are in a valve closed position. In another embodiment of the invention a plug member is secured to the reagent package for passage through the valves when the valves are in an open position to provide a leak proof seal of the container. 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 well and complementary engaging wall of the filter. Liquid can thus flow into the filter well through the micro-slits.
