Basic Sample Holder with a metal contact works as an electrical conductor between an electrode material (free-standing or deposited on a substrate) and an external circuit. This holder consists of PEEK body, pure Tantalum or Stainless Steel 316L metal electrical contact and PEEK screw to fix the electrode. It is compatible with most of inorganic and organic based plates, free-standing membranes or thin films deposited on flexible and rigid substrates. A maximum thickness of the sample is 4 mm. Tantalum is known to be inert to practically all organic and inorganic compounds. Tantalum’s corrosion resistance is very similar to that of glass, as both are unsuitable for use in hydrofluoric acid and strong hot alkali applications. Therefore in those cases we recommend Stainless Steel 316L wire contact variant.  The metal contact can be fully immersed in the electrolyte.
