Abstract: The described invention is directed to a process and a device for the production of a specimen carrier (18) and to the specimen carrier (18) itself An easily manageable specimen carrier (18) for the measurement of tagged specimens (19) is produced by a device by means of a more economical process in which the detection sensitivity of C.sup.14 .beta.-radiation is substantially improved. A specimen carrier (18) of this kind with specimen locations (8) which are enclosed on all sides by sheets (2, 20) is provided in that a sheet (2) is provided with depressions (3), a specimen (19) is placed in each of these depressions (3), a second sheet (20) is placed upon the sheet (2) carrying the specimens (19) and/or the sheets (2, 20) are connected with one another (see FIG. 1).
