Pressure tapped hydrostatic Core Holder LEPTHYC series

The LEPTHYC Series are standard Hydrostatic type core holders employed in studies involving fluid displacement in porous media. These core holders incorporate pressure taps moulded in the Viton sleeve at specified locations along the longitudinal axis. This great feature permits pressure drop monitoring along the core’s length. Another great advantage is the application of both radial and axial (equal) confining pressures.

A cylindrical core sample is fitted into a Viton sleeve and mounted onto a fixed platen at one end while at the other end, there is a floating platen through which the fluid passes via a ¼” diameter tubing. 

This design enables firm contact between the platen and core sample for a wide range of core lengths. To change a core sample, the confining fluid must be drained, pressure taps removed and the end plug unscrewed by manually rotating it counter-clockwise. This will withdraw the entire assembly: fixed platen, sleeve, core and floating platen. Subsequently the core can be removed from the sleeve. Loading a new core sample is carried out by performing this procedure backwards.
