A clamping device () is provided for cartridge filtration modules () that have a distribution plate () with a feed channel (), a retentate channel (), a filtrate channel, and a first contact surface (). At least one filter cartridge can be clamped between a contact surface () of the distribution plate () and a clamping surface () of a clamping plate () that can be moved orthogonally to the contact surface (). The cartridge filtration modules () can be stacked on one another in an area of their distribution plates (). A common distribution plate () for adjacent filter cartridge arrangements can clamped against the contact surface (). Adjacent filter cartridge arrangements can be connected in a parallel circuit via the distribution plate (), and the cartridge filtration modules () that can be stacked on top of one another can be connected in series via the distribution plates ().

Cartridge clamping device

A filter holder for receiving filter cassettes () and a method for sterilizing the filter are provided. The filter holder has first and second parallel plates (). The first plate () is fixed and the second plate () is movable along at least one rail () by a drive () so that the filter cassettes () can be clamped between the plates () with a predefined clamping pressure. The drive () is designed to be removable. The at least one rail () has at least one tension rod () with a spring clamping element () so that the first and second plates () can be clamped with a pre-definable pressure against the filter cassettes ().
