2.955in Diameter Porous Stone, 0.50in Thick

This Porous Stone measures 2.955 inches (75.1mm) in diameter, 0.50 inches (12.7mm) thick, and is crafted from high-quality aluminum oxide. Designed for durability, the rigid disc supports cylindrical soil samples while enabling two-way fluid flow during testing.

We provide a wide range of Porous Stones ideal for laboratory geotechnical applications, including triaxial shear, permeability, direct shear, consolidation, and more.

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