1.953in Diameter Porous Stone, 0.25in Thick

1.953in Diameter Porous Stone, 0.25in Thick

This Porous Stone measures 1.953in (49.6mm) in diameter, 0.25in (6.4mm) thick, and is made from durable aluminum oxide. Designed for geotechnical testing, the rigid disc supports cylindrical soil samples while allowing two-way fluid flow.

We offer a comprehensive range of Porous Stones for various lab applications, including triaxial shear, permeability, direct shear, consolidation, and more. These stones facilitate water and permeant flow 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, our high-quality stones are ideal for accurate testing and are available for immediate shipment.
