ABSTRACT:
Sealed analyte test packs or cups 11 disposed in holding trays 21 arrayed in a drawer 42 are individually and selectively transferred to a carrying tray 43 at a coplanar loading station for subsequent conveyance to an automated biochemical analyzing apparatus. An x/y scanning mechanism 46 is disposed above the drawer and tray to implement the transfers using a vacuum head 50 mounted on a movable plate 47 of the mechanism which is lowered onto the seal of a selected test pack and then raised to remove the pack from its holding tray. The plate also mounts an IR photo reflector 49 for detecting the test packs and a bar code sensor 48 for reading the holding tray labels. The array of trays is initially scanned to read their labels and establish a location map in a computer memory, which is subsequently updated during the transfer operations.
