2.8in Diameter Bronze Porous Stone, 0.25in Thick

2.8in Diameter Bronze Porous Stone, 0.25in Thick

This Bronze Porous Stone measures 2.8in (71.1mm) in diameter and 0.25in (6.4mm) in thickness, made from durable sintered bronze. It functions as a rigid disc that supports both ends of cylindrical soil samples while enabling two-way fluid flow.

Our selection of Porous Stones is designed for a wide range of geotechnical laboratory applications, including triaxial shear, permeability, direct shear, consolidation, and more.

Porous stones facilitate the flow and measurement of water or other permeants during testing while preventing fine particles from entering the system. High-quality stones offer 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 0.25in (6.3mm) or 0.5in (12.5mm) thicknesses.
• Sintered Bronze Round Porous Stones: Offered in common sizes with thicknesses of 0.125in (3.2mm) or 0.25in (6.3mm).
• Aluminum Oxide Square Porous Stones: Machined from aluminum oxide, these 0.25in thick stones are available in sizes from 1.953 x 1.953in (50 x 50mm) to 3.985 x 3.985in (101 x 101mm).
