Abstract: An apparatus, a system and a method for finding a direction of a radio tag having a transmitter and at least one antenna for sending signals to the apparatus. The apparatus including a receiver; at least one antenna capable to form at least two directivity fields; and means for determining the direction of the apparatus by a first path signal received from the radio tag by the at least two directivity fields of the at least one antenna of the apparatus. The direction is found by turning the apparatus to a direction of the most intense directivity field of the first path signal until the field intensities of the two directivity fields are equal.

Abstract: The invention relates to a sampling tube to which is fastened a memory device which is used to record data used to identify said sampling tube and/or its contents and the memory device being fastened to said sampling tube with a mounting piece. A mounting piece in accordance with the invention has a part which remains on the sampling tube or its part when the electronic memory device is attached to the sampling tube and/or detached from the sampling tube.

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.
