X-ray transparent core holders

X-ray transparent core holders are designed for X-ray scanners and computed tomographs, for studying the core samples reservoir properties at reservoir conditions.

X-ray transparent core holders can be the “dry” (Hassler) and submersible types. Core holder design provides 3-axis core compression by crimp pressure.

Depending on construction type, sample change in core holder takes place without draining or with partial discharge of hydraulic crimping fluid.

Core holders are equipped with special plungers through which samples pore pressure and pore fluids supply and filtration are created.
Core holders can be equipped with a separate heating system including band and clamp heaters, temperature sensors, temperature measurement and control system with a PC connection.
