Device and method for characterizing a capillary system

摘要

The present invention relates to a device for characterizing a capillary system in terms of wettability and geometry. The capillary pressure related to the presence of a meniscus inside an capillary system between a liquid/gas or liquid/liquid interface is measured. The pressure measuring device is comprising a capillary system, a liquid pump for pumping liquid into and out of a capillary system, a pressure sensor to measure the pressure of the liquid, and a tubing system for connecting the liquid pump, the pressure cell and the capillary system.
