ABSTRACT:
An improved sample holder for permeable materials, especially useful in permeameters. The sample holder contains the sample within a pliant sleeve. The sleeve is itself constained within a constrictor. When pressed into a seat, the constrictor reduces in diameter evenly along its length, holding the sample in the sleeve tightly without gaps for fluid leakage.
