Abstract
This concerns a core holder for a rock core in a resilient sleeve within a hollow housing. Longitudinal and radial forces are applied to the core. Fluid samples can be obtained at selected points along the length around the diameter of the core during injection of fluids therethrough. It concerns a special stem and seal for providing fluid or gas communication from within the resilient sleeve and the exterior of the housing.
