3.31in Diameter Porous Stone, 0.50in Thick

3.31in Diameter Porous Stone, 0.50in Thick

This Porous Stone measures 3.31in (84.1mm) in diameter, 0.50in (12.7mm) thick, and is made from high-quality aluminum oxide. Designed for geotechnical testing, its rigid structure supports cylindrical soil samples while allowing two-way fluid flow.

We provide a full range of Porous Stones suited for various lab applications, including triaxial shear, permeability, direct shear, and consolidation tests.

Porous Stones facilitate the flow and measurement of water or other permeants during tests while preventing fine particles from entering the system. These durable stones feature a permeability range of 15-18ft³ (424-510L) of air per square foot and an average pore size of 179µm. All Porous Stones are in stock and ready to ship.
