Stand-alone unit cell viewer

The unit cell viewer reads output files from PoreXpert (.pXt or .porexpert extension), and shows any unit cells within the output file in 3D virtual reality.  A range of structures are available from the datafiles download page. Alternatively you and your colleagues can view unit cells from your own saved PoreXpert output files.

To run the free viewer,  first register for access to the user download pages, or simply login there if you have already registered. Then download the .msi or zipped version of the installer.  The installer has been tested for viruses, and is signed by PoreXpert Ltd, so please respond positively to any firewall warnings.  Once installed, the viewer is very simple to use, and has optional built-in Help prompts that will switch on by default.


PoreXY is the PoreXpert porosimetry pre-processor, available free to all who register on this website. It corrects for and measures sample solid-phase compressibility (bulk modulus). It also allows easy trimming and thinning of data, for improved input to PoreXpert and easier calculation of the first derivative (slope) of the intrusion curve. Full details are given in its Help and Tutorial pages.
