Filtration device, method for assembling a modular filtration device, and method for characterizing a filter medium and/or a medium to be filtered

A filtration device having a plurality of filtration units, each filtration unit comprising:

• a first container designed to receive a medium to be filtered;
• a second container designed 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 first container is configured to be subjected to positive pressure, and
• wherein the second container is configured to receive a measurement instrument at ambient pressure.

A method for assembling a modular filtration device with a plurality of filtration units, comprising the steps of:

• attaching at least one filter medium to a connecting line plate;
• and
• arranging a container plate on the connecting line plate, the container plate comprising a plurality of first and second containers, wherein respective pairs of one of the first containers and one of the second containers are associated with a respective filtration unit, wherein the first container of a respective filtration unit is configured to receive a medium to be filtered and the second container of a filtration unit is configured to receive a filtrate,
• wherein the at least one filter medium is at least partially located between the connecting line plate and the container plate, and the respective first and second containers of a respective filtration unit are connected by one or more connecting lines of the connecting plate,
• wherein the first container of a filtration unit is configured to be subjected to positive pressure through a first opening, and
• wherein the second container of a respective filtration unit has a second opening through which a measurement instrument can be received in the second container at ambient pressure.

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, a 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 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.
