Abstract:
A reagent package comprising,a) a container having a top portion with an opening and a chamber for holding liquid,b) a generally hollow filter member in said chamber, said filter member having an upper open end and a lower open end axially aligned with said container opening such that liquid can be drawn out of said container from the hollow portion of said filter member, through the container opening and the upper open end of the filter member,c) said container having a floor with a recessed filter well defining the lowest portion of said chamber, said recessed filter well having a peripheral wall,d) said filter member having a liquid receiving bottom portion with the lower open end and an imperforate circumferential wall surrounding said lower open end, the bottom portion of said filter member and said peripheral well wall being of a complementary shape and size such that the lower open end of said filter member is disposable in said filter well to enable the imperforate circumferential wall of said filter member to have a surface contact area with the said peripheral well wall whereby any fragmentary solid material in said chamber is prevented from entering said filter well through said surface contact area and to enable substantially all liquid received in the bottom portion of the filter member within the filter well to be drawn out of the container through the upper open end of the filter member and the container opening.
