3.97in Diameter Porous Stone, 0.50in Thick

3.97in Diameter Porous Stone, 0.50in Thick

This Porous Stone measures 3.97in (100.8mm) in diameter, is 0.50in (12.7mm) thick, and is made from durable aluminum oxide. Designed to support cylindrical soil samples, the rigid disc facilitates two-way fluid flow during testing.

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

Porous Stones enable water and other permeants to flow and be measured during test procedures while reducing the risk of fine particles contaminating the system. Our 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.
