2.875in Diameter Porous Stone, 0.25in Thick
This Porous Stone measures 2.875in (73.0mm) in diameter and 0.25in (6.4mm) thick, made from durable aluminum oxide. Designed for use in geotechnical testing, it provides support for cylindrical soil samples while enabling two-way fluid flow.
We offer a wide range of Porous Stones for various laboratory applications, including triaxial shear, permeability, direct shear, consolidation, and more. These stones allow permeants like water to flow during testing and prevent fine particles from contaminating the system. With a permeability range of 15-18ft³ (424-510L) of air per square foot and an average pore size of 179μm, our high-quality stones are reliable and ready for immediate shipment.
