Abstract: Method and apparatus for encoding chemistry information on an identification device used to identify containers of biological matter such as blood samples, the apparatus including superimposed dies each having a plurality of rows of apertures, the apertures of one die being in alignment with the apertures of the other die, the dies being spaced one from another to receive the identification device between the dies. A stylus, having a tip for penetrating the identification device, is selectively inserted through the aligned apertures in the two dies thereby perforating (encoding) the device at one or more predetermined sites. Each perforation represents a chemical test or a set of tests to be performed on the biological matter in the container. A verifier is provided so that when the stylus perforates the device at a given site, an electrical circuit is completed to illuminate a corresponding portion of a display panel for optical indication to the operator of the true nature of the encoding which has taken place.
