1in Diameter Porous Stone, 0.25in Thick
This Porous Stone measures 1in (25.4mm) in diameter and 0.25in (6.4mm) in thickness, made from durable aluminum oxide. Designed to support cylindrical soil samples, it allows two-way fluid flow during testing.
We offer a wide range of Porous Stones for various geotechnical lab applications, including triaxial shear, permeability, direct shear, and consolidation testing.
Porous stones enable the flow and measurement of water or other permeants during testing while preventing fine particles from entering the system. Our high-quality stones have a permeability range of 15–18ft³ (424–510L) of air per square foot and an average pore size of 179µm. All options are in stock and ready to ship.
- Aluminum Oxide Round Porous Stones: The most popular choice, available in various diameters with 0.25in (6.3mm) or 0.5in (12.5mm) thickness.
- Sintered Bronze Round Porous Stones: Offered in popular sizes, with thickness options of 0.125in (3.2mm) or 0.25in (6.3mm).
