It is type of core holder names as Triaxial Coreholder Model JHR-Series . These core holders are generally used for free flowing liquids experiments. The device can be employed at following pressure rating of 5,000, 10,000 psi, 15,000 psi and a temperature up to 150C. The radial and axial loading are independent in these standard triaxial type core holders. The JHR series has a special feature in which the arm does not move and without even unloading or refilling, the limited fluid the core can be filled from one end. Using a floating plug the independent axial pressure is exerted. For introducing fluids and gases through core sample an incoming and outgoing distribution plug is used.
