Abstract
An automated chemical analyzer includes an automated conveyor apparatus for receiving a variety of sizes of test tubes, cuvettes, and sample tubes in a standard carrier member receivable into the analyzer. The standard carrier members may be interlocked in ranks and placed side by side in file to replicate the size and handling convenience of conventional test tube racks. However, the conveyor apparatus also provides for receipt of the carriers either as individuals for stat handling, or in interlocked ranks, or as rank and file groups for routine handling. The interlocked ranks of carriers are automatically unlocked from one another and fed along with the carriers having stat samples therein to a recirculating endless loop conveyor device which conveys the samples to at least one chemical analysis module, as well as providing a storage capacity both for samples in testing, and those samples awaiting verification of test results. Carriers with samples on which testing is completed and verified are discharged from the endless loop conveyor device into an off-loading facility which again interlocks the carriers and presents them in rank and file groups for subsequent handling like co…
