Tube i.e. capillary tube, for packaging preset volume of e.g. tissue sample, has annular end portion flatten by pinching receiving portion and adaptable such that lips are arrested relative to each other for forming heat seal of tube

摘要

The tube (1) has an annular end portion (3) flatten by pinching a receiving portion (2) receiving a preset volume of biological substance, where the tube is made of molded plastic material. The annular end portion takes a flattened position in which two lips (30) contact each other. The end portion is adaptable such that the lips are arrested relative to each other for forming a hermetic seal e.g. heat seal, of the tube. The receiving portion has a housing (7), which is occupied by a transparent resin (22) retaining an identification element (21) e.g. radio-frequency identification chip.
