Abstract: A bioprocessing filtration experiment system for filtering a liquid test medium as part of a filtration experiment in a filtration experiment section of the filtration experiment system, which filtration experiment section runs from a receptacle for holding the test medium to be filtered to a fluid outlet for the filtered test medium, wherein the filtration experiment system is designed to ascertain, as part of the filtration experiment, sensor data as experiment data for at least one filter, said experiment data being able to be taken as a basis for selecting and/or dimensioning the filter of a target system according to predetermined scaling criteria. It is proposed that the filtration experiment system can be preassembled on an at least partially programming-related and/or circuit-related, at least partially fluidics-related and/or at least partially sensor-related basis.
