| Zusammenfassung: | A pumping arrangement, for example for liquid chromatography, comprises a first liquid reservoir at a first height level, connected via a first hydraulic path to a pumping means; a second liquid reservoir at a second height level, connected via a second hydraulic path to the pumping means; and filtration devices arranged in the first and in the second hydraulic path. Each filtration device comprises an outer member (
1
) forming a first chamber (
6
), and an inner member (
2
) arranged within the outer member and forming a second chamber (
5
). The inner member (
2
) is porous and acts as a filter for liquid flowing from the first chamber to the second chamber. The arrangement ensures efficient filtering and prevents undesired backflow of liquid. |
