4.375in Diameter Porous Stone, 0.50in Thick
This Porous Stone measures 4.375in (111.1mm) in diameter, 0.50in (12.7mm) thick, and is made from durable aluminum oxide. Designed for laboratory use, the rigid disc supports cylindrical soil samples while allowing two-way fluid flow.
We provide a wide range of Porous Stones for various geotechnical testing applications, including triaxial shear, permeability, direct shear, and consolidation tests.
Porous stones enable fluid flow and measurements during testing while preventing fine soil particles from entering the system. High-quality 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.
