Test tube for biological analyses of organic liquids using electro-optical equipment

摘要

A test tube apparatus including a container body (1) with a cavity (3) which is essentially prismatic and has an essentially rectangular cross section, a cylindrical connecting part (5) for filling, and a flat laminar zone (7) developed as an extension of one of the walls of the cavity. Information which can be read optically, such as bar codes or the like, may be accommodated on this flat laminar zone (7).
