4.48in Diameter Porous Stone, 0.50in Thick

This Porous Stone measures 4.48in (113.8mm) in diameter and 0.50in (12.7mm) in thickness. Made from durable aluminum oxide material, it is designed to support cylindrical soil samples while enabling two-way fluid flow.

We provide a wide range of Porous Stones for various geotechnical lab applications, including triaxial shear, permeability, direct shear, and consolidation tests. These stones facilitate the flow and measurement of water or other permeants during testing while preventing fine 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 items are in stock and ready for immediate shipment.
