H2-Brine centrifuge coreholders for H2-brine capillary pressure determination
Description
The H₂ overburden coreholders designed for the RC4500 centrifuge enable capillary pressure measurements on core samples under both pore and confining pressures at reservoir temperature. They are vital for investigating the capillary behavior of binary brine/H₂ systems in hydrogen storage research, where maintaining stable pore pressure is crucial due to the presence of H₂. Each coreholder is equipped with a sapphire tube and a high-pressure needle valve, ensuring both durability and reliable performance under high-pressure conditions.
