Potting apparatus for a gas exchanger

A method of producing a potting for a gas exchanger under influence of a centrifugal force, the method comprising:

• inserting gas exchanger elements into an inner cavity of a cassette;
• mounting on the cassette a distributor having an opening and at least one continuous channel such that the opening of the distributor is fluidly connected via the at least one channel to the cavity to form a casting device for producing the potting for the gas exchanger, wherein the distributor defines an overflow region which is arranged and shaped such that excess material in the inner cavity flows into the overflow region in an assembled state of the distributor;
• and
• feeding a potting material into the opening under influence of a centrifugal force, wherein mounting the distributor on the cassette comprises assembling distributor components to define the opening of the distributor, to define the overflow region, and to form the at least one channel between adjacent regions of the distributor components.
