2.8in Diameter Porous Stone, 0.50in Thick

2.8in Diameter Porous Stone, 0.50in Thick

This Porous Stone, made from high-quality aluminum oxide material, measures 2.8in (71.1mm) in diameter and 0.50in (12.7mm) in thickness. Designed for durability, it supports cylindrical soil samples while enabling two-way fluid flow.

We offer a full range of Porous Stones tailored for laboratory geotechnical testing, including triaxial shear, permeability, direct shear, and consolidation tests. These stones facilitate the flow and measurement of water or other permeants during tests, while preventing fine particles from entering the system. With a permeability range of 15-18ft³ (424-510L) of air per square foot and an average pore size of 179µm, these stones ensure reliable performance. All are in stock and ready to ship.
