1.91in Diameter Porous Stone, 0.25in Thick

Porous Stone Specifications and Applications

This Porous Stone is crafted from high-quality aluminum oxide, featuring a 1.91in (48.5mm) diameter and a thickness of 0.25in (6.4mm). Designed for precision, the rigid disc supports both ends of cylindrical soil samples while enabling two-way fluid flow.

We provide a wide selection of Porous Stones tailored for various geotechnical lab applications, including triaxial shear, permeability, direct shear, and consolidation tests.

Porous stones ensure efficient water and fluid flow during testing while preventing fine particles from entering the system. These durable stones have a permeability range of 15–18ft³ (424–510L) of air per square foot and an average pore size of 179μm. All stones are in stock and ready for immediate shipment.

Types of Porous Stones:

• Aluminum Oxide Round Porous Stones: The most popular option, available in a wide range of diameters with thicknesses of 0.25in (6.3mm) or 0.5in (12.5mm).
