High-Pressure Triaxial Cells

High-Pressure Triaxial Cells are available for use with sample sizes from 1.4" (35mm) to 2.8" (71mm). The clear acrylic chamber has a working pressure of 500 psi (3,500 kPa) and is tested to 550 psi (3,800 kPa). This high-pressure cell includes the addition of 4 metal bands to maintain integrity of the test chamber during testing. The design features a solid base, which provides an extremely stable test platform making it faster and easier to center the cell on the load frame platen— reducing setup times. This cell provides easy access to the test chamber by utilizing a one-piece, chamber unit that is quickly removed through the removal of three easy-turn knobs. These cells also have an integral de-airing block for the pore pressure transducer built into the side. The cells have five no-volume-change valves aligned on one side for maximum convenience. Two valves handle top drainage, two valves handle bottom drainage, and one valve handles filling and drainage, as well as providing confining pressure to the cell. The removable base pedestal accommodates various sample diameters. Top caps and base pedestals are available in black-anodized aluminum or stainless steel in various sizes (see chart below). Other sizes are available. The cell top and base are precision machined from 6061 T6 aluminum, black anodized for a durable finish. A .625" hardened stainless steel piston runs inside a linear bearing to reduce friction. Choice of brass or stainless steel valve fittings is also available (stainless steel for use with hazardous materials).

The 4" version of our High-Pressure Triaxial Cell is identical in construction to our 3" model. It is designed for use in testing samples up to 4" (100mm) samples in high-pressure applications up to 500psi or (3,500 kPa). This cell also features the addition of 4 metal bands to maintain integrity of the test chamber during testing and is available in stainless steel too.
