For characterization of pores and fractures within rocks the laboratory is equipped with an X-Ray computer tomography system (Nanotom CT), He-gas pycnometer (AccuPyc), Hg porosimeter (2000 WS), and a gas adsorption porosimeter (TS Surfer). For damage-free preparation of 1 - 2 mm² large, almost planar surfaces, a broad ion beam (BIB) polisher operating with an Ar-Ion beam is operated.
