CT-TC Series
Coretest Triaxial Pressure Cell Series
Coretest triaxial pressure cells apply controlled confining pressure to jacketed cylindrical rock specimens. The series covers passive cells for use in an external loading frame, integral-deviatoric configurations, pressure-balanced designs, Hoek cells, acoustic measurement cells and quick-release systems.

- Pressure-rated cell body for jacketed cylindrical specimens
- Confining-fluid inlet, pressure measurement and controlled venting interfaces
- Axial loading through a host frame or integral actuator, depending on configuration
- End platens and feedthroughs selected for the required pore-pressure, strain, acoustic or electrical measurements
- Seal and wetted-material selection based on pressure, temperature and fluid compatibility
Configuration and Engineering Options
- Specimen diameter and length
- Maximum confining pressure and axial-load envelope
- Ambient, heated or application-specific temperature configuration
- Local axial and radial strain measurement
- Pore-pressure, permeability and flow interfaces
- Ultrasonic, acoustic-emission or electrical feedthroughs
- Corrosion-resistant wetted materials and application-specific seals
