The present invention relates to a method of radiolabelling carbon nanotubes, to the radiolabelled carbon nanotubes that can be obtained by implementing this method, and to applications thereof. It is distinguished in that the electrode line comprises an intrinsically conductive polymer in which the individual polymer chains of the polymer are so oriented that there is a high electrical conductivity in the axial direction of the electrode line but not in the radial direction. In the hard coat, the content of the inorganic filler in the surface of the hardcoat is higher than that in the interior of the hardcoat. Measured link subsystem performance characteristics may be gathered and stored in a database as probability distribution functions. Also, the unsealing impetus can be controlled by the strength of material used for the first part to make the set up of the prevention of liquid splash possible at the time of unsealing. A surge tank is coupled to an outlet of the vacuum centrifuge, wherein the mixture is dispersed from an outlet of the surge tank.
