A synthesis route towards free standing graphene membranes is presented. Using this electron transparent material, so called ambient pressure cells can be constructed that seal vacuum incompatible samples in ultrahigh vacuum, which then can be characterized by photoelectron spectroscopy. Systematic optimization of the process parameters during chemical vapor deposition of graphene on Cu-foils enables the synthesis of high quality graphene films. The transfer of grown films from the Cu-substrate onto prestructured supports leads to a reliable synthesis route of graphene membranes.
