Abstract: The subject of this invention is a specimen identifier, which consists of a base section (1), which allows the specimen identifier to be placed on a surface, an identifier memory unit (2) for identifying the specimen, which fits conveniently into the base section, and a mounting section (3) for mounting the test tube (4) in the specimen identifier. According to the invention, the specimen identifier includes a middle section (5) between the base section (1) and the mounting section (3), and mounting grips (3) forming the mounting section positioned a short distance from the base section (1) which expand to the sides, are curve-shaped and manufactured from a flexible material, and whose arms are a distance apart from each other and between which the test tube can be mounted.
