The Ultrapyc gas pycnometer (Anton Paar Ultrapyc 5000 Micro) can be used to measure the density of solid and semi-solid substances to determine the purity or porosity of samples. Samples with a volume of only 0.25 cm³ (but also larger samples of 1-3 cm³) can be measured with a maximum deviation from the accuracy of ~1%. The device is equipped with a balance and can be used on request.

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.
