A reconfigurable nest handling system for handling nests of objects arranged in a predetermined pattern is presented and applied to a system for filling nested pharmaceutical containers with a pharmaceutical fluid. In one general aspect, the system comprises a sterilizable chamber containing a planar rotary stage with tub and nest positioning systems that may be reconfigurable for holding differently sized pharmaceutical container tubs and nests and pharmaceutical closure tubs and nests. The chamber has a rotatable cover removal station, a rotatable filling station with a dispenser head, and camera guided vacuum pickup facilities for handling container and closure nests. The vacuum pickup facilities may be reconfigurable for handling differently sized nests. An associated method for filling the containers comprises establishing an aseptic condition within the chamber; removing covers from a container tub and a container closure tub by operating both the rotary stage and the cover removal station. The vacuum pickup facility transfers into the fiducial locating structure a container nest bearing pharmaceutical containers. The fluid is dispensed into the containers by operating both the rotary stage and the filling station. A container closure nest is placed on the container nest in the fiducial locating structure with closures in correspondence with containers. A ram in the chamber forces the closures into the containers.
