4in Diameter Porous Stone, 0.25in Thick

4in Diameter Porous Stone, 0.25in Thick

The Porous Stone is designed for geotechnical testing applications, offering durability and precision. This round stone measures 4in (101.6mm) in diameter, 0.25in (6.4mm) thick, and is made from high-quality aluminum oxide. Its rigid structure supports cylindrical soil samples while enabling two-way fluid flow.

We provide a wide range of Porous Stones for laboratory geotechnical tests, including triaxial shear, permeability, direct shear, and consolidation. These stones allow water and other permeants to flow through while preventing fine particles from entering the test system. With a permeability range of 15-18ft³ (424-510L) of air per square foot and an average pore size of 179µm, our stones deliver reliable performance. All options are in stock and ready for immediate shipment.
