17. Apparatus for maintaining gas in a predetermined pressure range during a gas exchange process which apparatus includes:
-
a first circulating conduit having a gas permeable membrane wall portion;
at least one inlet port for introducing a first gas into the apparatus; and
a reservoir arranged to contain the first gas, the reservoir being in communication with the circulating conduit, wherein the conduit is arranged such that substantially all of the first gas circulating in the first conduit exit the conduit via the gas membrane. - View Dependent Claims (18, 19)
