Abstract: The invention relates to a method for testing the interaction between at least one liquid sample and a respective solid sample. The method comprises at least the steps of—providing adjacent first and second cavities, where said first and second cavities are in mutual communication via at least one passage, —placing the solid sample in said first cavity, —introducing the liquid sample in one of said first and second cavities, —sealing at least said first and second cavities from the exterior, so as to form a closed system of communicating cavities, —bringing said liquid sample into contact with the solid sample in said first cavity, transferring substantially all of said liquid sample to the second cavity after it has been brought into contact with the solid sample, —and testing the desired properties of any one or both of said liquid sample or said solid sample.
