Triaxial Test Cells for 1.4in to 4in (35.6 to 101.6mm) maximum diameter specimens come equipped with rugged quality brass or stainless steel valves and fittings. They offer optimal performance with HM-350M Master Control Panel or HM-350A Auxiliary Control Panel, as well as other triaxial testing systems.
The Test Cells are built with a solid, machined-aluminum base to handle heavy loading, and the chamber is constructed of heavy-wall clear acrylic with a 5.0x12.125in (127x308mm) interior. The precision-ground and polished stainless steel load piston features internally lubed and sealed U-cup and nylon sleeve bearings for very low friction. Cells are equipped with precision zero-volume change ball valves and have a maximum operating pressure of 150psi (10.3bar).
HMA-518 Triaxial Test Cell includes brass valves and fittings.
HMA-518S Triaxial Test Cell comes with stainless steel valves and fittings to withstand corrosion and harsh permeant fluids.
A size-specific Test Cell Kit is required for testing 1.4 to 4in soil specimens with HMA-518 models, and available separately from the Triaxial Cell Accessories page. Each kit contains components that correspond to the specimen size and includes an anodized aluminum cap and pedestal, two Porous Stones, two Latex Membranes, and four O-Rings. Also available separately is HMA-521 Digital Pore Pressure Gauge w/Transducer.
