Reagent container for an automated analyzer
First Claim
1. A reagent container for use in an automated assay analysis system comprising:
- a bottom wall;
a tubular vertical section having a vertical axis and formed of a side wall of circular cross-section connected to the bottom wall to define an inner chamber;
a top opening of the tubular section;
a tubular outer skirt of circular cross-section being coaxial with and of a greater diameter than the tubular vertical section, the skirt being attached to the side wall of the tubular section and extending downwardly from the side wall and terminating in a bottom edge below the bottom wall; and
at least one fin located in the inner chamber and attached to and extending from the bottom wall and attached to and extending from a portion of the side wall that extends along the major length of the side wall, for agitating fluid within the chamber upon rotation of the tubular vertical section about the vertical axis.

Abstract
An analyzer for performing automated assay testing. The analyzer includes a storage and conveyor system for conveying cuvettes to an incubation or processing conveyor, a storage and selection system for test sample containers, a storage and selection system for reagent containers, sample and reagent aspirating and dispensing probes, a separation system for separating bound from unbound tracer or labeled reagent, a detection system and date collection/processing system. AU of the sub-units of the machine are controlled by a central processing unit to coordinate the activity of all of the subunits of the analyzer. The analyzer is specifically suited for performing heterogeneous binding assay protocols, particularly immunoassays.

8. A reagent container comprising:
-
an enclosure having a bottom wall and a tubular vertical section, the tubular vertical section having a vertical axis and a top opening, the tubular vertical axis being formed of a side wall of circular cross-section having a predetermined internal diameter, the side wall connected to the bottom wall to define an inner chamber within the enclosure;
a tubular outer skirt of circular cross-section being coaxial with and of a greater diameter than the tubular vertical section, the tubular outer skirt being attached to the enclosure and extending downwardly and terminating in a bottom edge below the bottom wall;
at least one fin located in the inner chamber and attached to and extending from the bottom wall and attached to and extending from a portion of the side wall that extends along the major length of the side wall, for agitating fluid within the inner chamber upon rotation of the enclosure; and
a cover having a flat annular portion and a stepped portion attached thereto, the stepped portion being circular and having a diameter that corresponds approximately to the predetermined internal diameter of the side wall, the flat annular portion being located circumferentially around the stepped portion and extending radially outwardly from the stepped portion to have an outer diameter that is greater than the predetermined internal diameter of the side wall, and the flat annular portion resting on the top opening of the tubular vertical section and the stepped portion fitting snugly within the side wall adjacent the top opening. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A reagent container comprising:
-
an enclosure having a bottom wall and a tubular vertical section, the tubular vertical section having a vertical axis and a top opening and being formed of a side wall of circular cross-section having a predetermined internal diameter and connected to the bottom wall to define an inner chamber within the enclosure;
a tubular outer skirt of circular cross-section being coaxial with and of a greater diameter than the tubular vertical section, the tubular outer skirt being attached to the enclosure and extending downwardly and terminating in a bottom edge below the bottom wall; and
a pair of thin coplanar fins located in the inner chamber and attached to extending from the bottom wall and attached to and extending from opposite sides of the side wail along the major portion of the length of the side wall, for agitating fluid within the inner chamber upon rotation of the tubular vertical section, the thin fins extending toward one another and toward the vertical axis of the tubular vertical section from opposite locations on the side wall. - View Dependent Claims (16, 17, 18, 19, 20, 21)
