LINSEIS High-Pressure Measuring Devices

High-Pressure Measuring Devices by Linseis are advanced thermal analysis systems designed to perform precise material characterization under extreme pressure conditions, up to 150 bar, while maintaining the same measurement principles and accuracy as ambient-pressure instruments.

These systems enable thermal analysis under realistic industrial and research conditions, making them ideal for studying pressure-dependent phenomena such as sorption, decomposition, phase transitions, and chemical reactions. Linseis high-pressure analyzers support key techniques including DSC, TGA, STA (TG-DSC/DTA) and high-pressure dilatometry, covering applications from hydrogen technology to biomass gasification and chemical process optimization.

High-pressure thermal analysis is of critical importance in renewable energy research, particularly for hydrogen storage, where storage materials (e.g. metal hydrides) must be evaluated as a function of pressure, temperature, and gas atmosphere. Similarly, these systems allow simulation of industrial processes such as biomass gasification, where pressure, temperature, and gas composition directly influence syngas production.

All Linseis high-pressure systems are vacuum-tight, compatible with reactive, inert, oxidizing or reducing atmospheres, and offer fully controlled pressure, temperature, and gas composition for reproducible and application-relevant measurements.
