Hassler Core Holder

Manufacturer: Vinci Technologies
Model Number: HAC

The HAC Series core holders are standard Hassler type core holders used for fluid flow testing. With the coreholder assembled and the sleeve in place the core is inserted into the loading end. The platen is then pushed in and held in place by the cap which can be screwed on by hand and allows 50 mm adjustement. Further adjustment is possible with the use of interchangeable spacers fitted to the loose platen. An inlet and outlet distribution plug allows fluids and gases to be injected through the core sample. A unique feature of the HAC series core holder is that the sleeve remains in place and the core is loaded from one end without having to drain or refill the confining fluid. By releasing the confining radial pressure and unscrewing the end plug, the core sample can be easily removed without exposing it to the annulus fluid. The core holders can be provided to have interchangeable core diameters. The coreholder can be equipped with a number of pressure taps molded in the sleeve at discrete locations required by the end user. This design allow to monitor the pressure drop along the length of the core sample during fluid flow tests. Electrical pressure tap can also be provided to monitor the resistivity of the core sample during a permeability test.
