HAC-series Hassler Core Holder


The HAC Series are standard Hassler type core holders employed in studies involving fluid displacement in porous media. A cylindrical core sample is fitted in a Viton sleeve and inserted into the core holder via the loading end. A platen is then pushed against the core end face and maintained by a threaded cap allowing up to 30 mm length adjustments. Further adjustments are possible by means of interchangeable spacers pressed against the loose platen. An inlet and outlet distribution plug allows fluids and gases to be injected through the core sample. A convenient characteristic of the HAC series core holder is that the sleeve remains inside the core holder; the core is loaded from one end without the need of filling/draining the confining fluid. By releasing the confining pressure and unscrewing the end plug, the core sample can easily be removed without hydraulic fluid exposure.
