Figure F2. A. Schematic of the permeability test system. B. Labeled photo of the permeability test system. The top, bottom, and cell pumps from Geotac consist of 80 mL pistons that are moved upward or downward to infuse or extract water from the sample or cell. The 160 mL interface chamber has a rubber diaphragm in the center, which separates the saltwater that is used as a permeant (bottom chamber) from the distilled water used in the pumps (top chamber). Deionized (DI) water is used in the cell pump and in the sample cell, which has a volume of 2300 mL.
