An apparatus automatically determining the permeability and porosity for a plurality of core samples. The apparatus includes a carousel capable of carrying a plurality of core samples, a piston located under the carousel for selectively raising one of the core samples from the carousel into an upper sample holder wherein the piston in cooperation with the sample holder seals the core sample in a test chamber, and a second piston located internal to the first piston for selectively closing and opening the lower end of the core sample so that gas introduced in the upper end of the core sample can be utilized to conduct a permeability test when the lower end is open and a porosity test when the lower end is closed by the internal piston.
