The disclosed embodiments include a rock sample inspection method. The method may include preparing a sample of formation rock by encapsulating the sample, inserting the sample into a vessel body as part of a test assembly, enclosing the sample within an low compressibility fluid, applying pressure to an interior of the vessel body by tightening a compression screw employing a piston acting on said low compressibility fluid, monitoring the pressure, conducting a test on the sample, and recording results of the test for further analysis.
