HTRX-010 Quick Triaxial Cell

The GCTS HTRX-010 Quick Triaxial Cell was engineered for fast and easy testing of rock cores within certain parameters. This triaxial cell is ideal for classrooms.


  • 35 MPa (5,000 psi) pressure & 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.
  • Accepts samples with a 25 mm (1 inch) or 38 mm (1.5 inch) diameter and with a length of 2 times the diameter (one different set of platens required for each size).

The GCTS Quick Triaxial Cell was designed for fast and easy testing of rock cores with a 25 mm (1 inch) or 38 mm (1.5 inch) diameter. The triaxial cell has a membrane built-in 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 gages onto the specimen to measure radial strains. Axial strains are measured with two averaging vertical LVDTs.


GCTS offers economical loading frames that are manually operated (hand pump) to apply axial loads up to 300 kN. The HTRX-010 triaxial cell fits inside the GCTS Point Load tester frame. GCTS also offers several different pumps (manual and automated) for applying the cell pressure. The complete system (triaxial cell, loading frame, and data acquisition) fits inside a carrying case.


The included automatic data acquisition with USB interface allows the connection to a Laptop or PC computer for real time display of stress-strain curves. The HTRX-010 is ideal for the classroom.
