2.5in Diameter Porous Stone, 0.50in Thick

2.5in Diameter Porous Stone, 0.50in Thick

This Porous Stone is made from high-quality aluminum oxide, measuring 2.5in (63.5mm) in diameter and 0.50in (12.7mm) thick. Designed for geotechnical applications, the rigid disc supports cylindrical soil samples while enabling two-way fluid flow.

We offer an extensive range of Porous Stones for various geotechnical testing, including triaxial shear, permeability, direct shear, and consolidation tests.

Porous Stones facilitate fluid flow during testing while minimizing fine particle intrusion into the system. Our premium stones have a permeability range of 15–18ft³ (424–510L) of air per square foot, with an average pore size of 179µm. All products are in stock and ready to ship.
