Claim 16:
17. A method for characterizing a filter medium and/or a medium to be filtered, comprising the steps of:
arranging a filtration device having a plurality of filtration units on a pipetting robot, each filtration unit respectively comprising:
a first container configured to receive a medium to be filtered,
a second container configured to receive a filtrate,
at least one connecting line connecting the first container to the second container, and
a filter medium between the first container and the second container in order to filter the medium to be filtered;
wherein the at least one connecting line comprises a fluid passageway and a flow direction of the medium through the at least one connecting line changes as the medium flows from the first container to the second container,
wherein the first container is configured to be subjected to positive pressure, and the second container is configured to receive a measurement instrument at ambient pressure;

applying positive pressure to at least a part of the first containers of a plurality of filtration units in order to filter the medium to be filtered through the filter medium and transfer it into a corresponding second container; and
measuring the filtrates at ambient pressure in at least a part of the second containers by means of an introduced measurement instrument.
