Welcome!
Gesteinslabor Dr. Eberhard Jahns has great expertise for all questions related to geomaterial testing. Our laboratory is a leading provider of physical and mineralogical analyses of rocks and other mineral materials

The focus of our service is the conducting of rockphysical and rockmechanical laboratory experiments. Apart from the standard experiments for determining the rockmechanical characteristics, we are specialists in solutions to customer-specific requirements with individual, challenging test procedures.
We apply for many years now highest-level in testing technology, hence you can rely on our laboratory experience of standard and special solutions for your testing requirements. We would be happy to develope testing paths which match exactly your requirements and problem solutions.

The DGMK/ÖGEW spring conference is on the road for the second time, and – as always – we’ll be there!
Come and see us in Münster at Stand 32 on the upper floor; we look forward to seeing you!

Gesteinslabor Dr. Eberhard Jahns is project and research partner within the HENRI (Hydrogen Energy Reservoir) project.
Our main focus is on determining the impact of H2 on the cap rock. Besides other parameters, we measure the capillary threshold pressure using various gases and gas mixtures of hydrogen and methane.
Results were presented at the third HENRI conference in Bratislava in September 2025
We are pleased to be part of the Dutch subsurface research for geothermal heat SCAN.
