4.375in Diameter Porous Stone, 0.25in Thick

This Porous Stone measures 4.375in (111.1mm) in diameter, 0.25in (6.4mm) thick, and is crafted from high-quality aluminum oxide. Designed to support cylindrical soil samples, it facilitates two-way fluid flow during testing.

We offer a wide range of Porous Stones ideal for various geotechnical laboratory applications such as triaxial shear, permeability, direct shear, consolidation, and more.

Porous stones enable the flow and measurement of water or other permeants during testing while preventing fine particles from entering the system. These 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 ready for immediate shipment.

Available Options:

• Aluminum Oxide Round Porous Stones – The most popular choice, available in various diameters and in 0.25in (6.3mm) or 0.5in (12.5mm) thicknesses.
• Sintered Bronze Round Porous Stones – Offered in popular sizes with 0.125in (3.2mm) or 0.25in (6.3mm) thicknesses.
