Abstract: The present invention belongs to the field of nanotechnology, more precisely to the field of nanostructures formed by manipulation of individual atoms, molecules, and to manufacturing processes for providing said nanostructures. The invention relates to an apparatus for anodic oxidation of small metal grids, which comprises: − a housing comprising a bottom part and a top part arranged to receive a metal grid, wherein - each part is provided with an opening for allowing contact with an electrolyte, - one of the said parts is provided with a slot for receiving an electrical contact, said slot is arranged around the said opening, - at least one, preferably at least one, preferably both parts are provided with a slot for installation of a seal, preferably rubber seal, around the said opening, - each part having assembly means to assemble both housing parts together, − the electrical contact shaped as an elongated flat element with a circular head having a hole to receive the metal grid, said hole being slightly smaller than the metal grid to be anodized, wherein the elongated flat element is arranged to be connected to electricity, preferably using an alligator clip, and − preferably the metal grid, typically a TEM grid usually having a diameter or length up to 5 mm.
