A handling device for samples and reagents to be used in testing in a system. Carriers of samples and reagents are loaded on a platform which detects the presence of, and proper loading of, such carriers. The carriers are moved from the platform by a transporter to a bar code reader for identification. A reagent container is rotated during reading to facilitate identification. The transporter further moves identified reagent carriers to a carousel on which the carriers automatically secured for storage awaiting use in testing. The carousel rotates, and selected reagent containers rotate on the rotating carousel, during storage.
