1.88in Diameter Porous Stone, 0.25in Thick

1.88in Diameter Porous Stone, 0.25in Thick

This Porous Stone measures 1.88in (47.8mm) in diameter, 0.25in (6.4mm) thick, and is made from high-quality aluminum oxide material. Designed to support cylindrical soil samples, it allows two-way fluid flow during testing.

We provide a wide range of Porous Stones for laboratory geotechnical applications such as triaxial shear, permeability, direct shear, and consolidation tests.

Porous Stones facilitate water and permeant flow while preventing fine particles from entering the test system. With a permeability range of 15-18ft³ (424-510L) of air per square foot and an average pore size of 179μm, these durable stones are precision-engineered for reliable performance. All models are available for immediate shipping.

Types of Porous Stones:

• Aluminum Oxide Round Stones: The most popular option, available in a variety of diameters and two thicknesses (0.25in / 6.3mm or 0.5in / 12.5mm).
• Sintered Bronze Round Stones: Offered in popular sizes with thicknesses of 0.125in (3.2mm) or 0.25in (6.3mm).
• Aluminum Oxide Square Stones: Machined from aluminum oxide, 0.25in thick, available in sizes from 1.953 x 1.953in (50 x 50mm) to 3.985 x 3.985in (101 x 101mm).
