A specimen-transport module adapted for use with each of a plurality of specimen-processing instruments of a multi-instrument clinical workcell. Such module is adapted to transport individual racks of specimen-containers relative to a specimen-aspiration probe of an associated instrument in a workcell, as well as to transfer selected racks of specimen-containers to an adjacent and identical specimen-transport module associated with another clinical instrument of the workcell. Since the same transport system is used to both present specimens for aspiration and to transfer specimens between instruments, there is no need for two independent conveyances as is characteristic of the prior art. Preferably, the specimen-transport module includes a magnetic X/Y transport system that operates beneath a rack-supporting surface to advance racks in mutually perpendicular directions across a supporting surface via magnetic forces.

An intelligent rack automatically detects the position of a specimen tube within a multiple specimen tube containing rack such as that utilized within automatic specimen processing apparatuses. The rack has a plurality of positions with a moving element located adjacent each position. The moving element, such as a spring, is positioned so that it moves when a specimen tube is placed within an adjacent position. A magnet or other sensor on the moving element interacts with a detector to sense when a particular position has received a specimen tube. A computer controlling the apparatus receives specimen information for each specimen tube and has an identifier for the specimen tube, such as a bar code, scanned into the computer before placement of the specimen tube into a rack position. Removal of the specimen tube from a position on the rack causes correlating removal of specimen tube position information from the computer.

A sample processing system that may be configured to achieve parallel or coincidental sample processing such as histochemical processing may involve a plurality of samples arranged for coincidental movement perhaps by use of angular microscopic slide movements to cause processing activity that may include repeated elimination and reapplication of a fluidic substance perhaps through the action of capillary motion in order to refresh a microenvironment adjacent to a sample such as a biopsy or other such sample. Snap in antibody and other substances may be included to ease operator actions and to permit location specific substance applications perhaps by including single container multiple chamber multiple fluidic substance magazines, linearly disposed multiple substance source, and primary antibody cartridges. Through refreshing of a microenvironment, depletion of the microenvironment is avoided and the time necessary for slide processing may be dramatically shortened from a more common 60 to 120 minutes to perhaps less than 15 minutes so as to permit use of such a system in an intraoperative or surgical environment such as recommended by the College of American Pathologists intraoperative guidelines or the like. Patients may thus avoid a need to be subjected to an additional surgical procedure when lab results become available to see if tumors or the like were fully removed in a prior procedure.
