Sample preparation
The basic precondition for a standards-compliant strength examination is exact manufacturing of the specimen body. What is important above all is the right-angularity of the end surfaces of the specimen to the specimen axis (i.e. their perfect parallelism).
At Gesteinslabor Dr. Eberhard Jahns, this task is taken care of by a customised abrasive cutting-off machine with frequency-controlled automatic feeding. Specially developed clamping devices facilitate exactly plane-parallel cutting steps without the specimen having to be released from the clamps. The closed system allows, if required, the execution of dry cuts without any problems, to avoid interaction between the rock material and the cooling fluid.

DGMK/ÖGEW spring conference 2025 goes on tour and we are part of it!
Meet us on booth 2, we look forward to a lively exchange in Papenburg.
Gesteinslabor Dr. Eberhard Jahns is project and research partner within the HENRI (Hydrogen Energy Reservoir) project.
Main focus of us is the impact of H2 on the cap rock. Besides other parameters, we determine the capillary threshold pressure with different gases and gas mixtures.
First preliminary results could be presented at the 2nd HENRI conference.
Recently, the article "Determination of capillary threshold pressure with hydrogen gas" was published in the journal EEK.
Article from the journal EEK 01/2023
Gesteinslabor has successfully completed the development of a new test rig to determine the capillary threshold pressure with hydrogen.
