1.35in Diameter Porous Stone, 0.25in Thick
This Porous Stone measures 1.35in (34.3mm) in diameter and 0.25in (6.3mm) thick, crafted from durable aluminum oxide material. Designed to support cylindrical soil samples, it enables two-way fluid flow during testing.
We offer a full range of Porous Stones for geotechnical laboratory applications, including triaxial shear, permeability, direct shear, consolidation, and more.
Porous Stones allow the flow and measurement of water or other permeants during testing while minimizing the risk of fine particles entering the system. 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 Porous Stones are in stock and ready to ship.
- Aluminum Oxide Round Porous Stones: The most popular option, available in various diameters with thicknesses of 0.25in (6.3mm) or 0.5in (12.5mm).
- Sintered Bronze Round Porous Stones: Offered in several sizes, with thicknesses of 0.125in (3.2mm) or 0.25in (6.3mm).
