3.99in Diameter Porous Stone, 0.25in Thick

3.99in Diameter Porous Stone, 0.25in Thick

The Porous Stone, made from high-quality aluminum oxide, measures 3.99in (101.3mm) in diameter and 0.25in (6.4mm) in thickness. Designed for geotechnical lab applications, it supports cylindrical soil samples while enabling two-way fluid flow during testing.

We provide a wide range of Porous Stones for tests like triaxial shear, permeability, direct shear, consolidation, and more. These stones ensure smooth fluid flow 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 porous stones are both reliable and efficient. All options are available for immediate shipment.

Available Types:

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