High Pressure Triaxial Cell
Testing accessories and preparation equipment
QTRX-70 Quick High Pressure Triaxial Cell


  • 70 MPa (10,000 psi) pressure and 500 kN (100 kips) axial load capacity
  • Quick “drop-in” specimen setup
  • Axial and radial strain measurements
  • Upper platen provided with a spherical seat to compensate for non-parallel specimen ends
  • Hardened stainless steel construction
  • Bottom pore pressure plumbing provided for effective stress measurements
  • Includes triaxial software and automatic data acquisition with USB interface
  • Accepts samples with a diameter of 25 mm (1 in.) or 38 mm (1.5 in.) and with a length of 2 times the diameter (one different set of platens and membrane retainer is required for each size)

The GCTS Quick Triaxial Cell (QTRX-70) is designed for fast and easy testing of rock cores with a diameter of either 25 mm (1 inch) or 38 mm (1.5 inch). The triaxial cell has a built-in membrane where specimens are simply dropped inside from the top. Three lateral actuators instrumented with LVDTs that are pressure compensated ensure a firm contact with the specimen to precisely measure the radial strains. The LVDTs eliminate the time-consuming task of gluing strain gauges onto the specimen to measure radial strains. Axial strains are measured with two averaging vertical LVDTs.
