ABSTRACT:
A device for identifying the content of a straw formed of a heat-sealed section of ionomer resin tube offering high performance at cryogenic temperatures comprises a sheath length threaded onto the straw and trapped between the ends of the straw which are flattened and widened in the transverse direction on sealing the straw after filling. The sheath carries printed identifying data and its color facilitates identification. This avoids the possibility of defective printing on the ionomer resin and damage to the straw or its contents by diffusion of constituents of the ink. The sheath can be ovalized at one end to prevent it moving freely.
