20.08.2026 · New Possibilities for Rock Analysis

With the recent acquisition of the state-of-the-art DIL 502 Expedis® Select thermal dilatometer from Netzsch, we are expanding our capabilities for the precise analysis of the thermal properties of rocks and mineral materials. We are now able to determine the coefficient of thermal expansion in accordance with DIN EN 14581:2004, ASTM D4535-13e1. (2013) or using a measurement program specifically tailored to the customer’s needs (for more information, see Thermal Dilatometer).

The project, which was funded by the Free State of Thuringia, was co-financed by the European Union through the European Regional Development Fund (EFRE).

14.08.2026 · GET2026

This year’s EAGE GET Conference and Exhibition is taking place in Germany:

Logo Get2026

Gesteinslabor Dr. Eberhard Jahns will again be taking part as an exhibitor this year. From 2 to 6 November 2026, you can find us at Stand 31 at the HCC in Hannover.

We would be delighted to welcome you to our stand.

03.02.2026 · Project HENRI

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

 

23.06.2025 · SCAN

 

We are pleased to be part of the Dutch subsurface research for geothermal heat SCAN.
