Abstract: Device for producing or for storing a fluid stream from m greater than 1 fluid segments, which are respectively separated by a transmitting medium (3) not mixable with the fluid segments, comprises a molding (2), which possesses a channel (21) for guiding the fluid stream, from which n greater than 1 first entrances (22a-22g) and n second entrances (23a-23g) branch in such a manner that these are more insertable in n recesses (11a-11g), where lengths of the first entrances differ from lengths of the second entrances. Device for producing or for storing a fluid stream from m greater than 1 fluid segments (4a-4g), which are respectively separated by a transmitting medium (3) not mixable with the fluid segments, comprises a molding (2), which possesses a channel (21) for guiding the fluid stream, from which n greater than 1 first entrances (22a-22g) and n second entrances (23a-23g) branch in such a manner that these are more insertable in n recesses (11a-11g), where lengths of the first entrances differ from lengths of the second entrances and where in the channel between the branch location of each second entrance and the branch location of each first entrance is attached with first valves (24a-24g) and each second entrance is attached to second valves (25a-25g). Independent claims are also included for: (1) an arrangement for producing or for storing of a fluid stream from m greater than 1 fluid segments, comprising the device mentioned above; and (2) producing or storing a fluid stream from fluid segments, comprising either (a) introducing intermediary mediums into the input of the channel and selecting from k of the n recesses (11x, x is equal to a-g), from which at least one part of first liquid phase is transferred as fluid segment into the fluid stream, closing the associated first valves and opening the associated second valves; (b) introducing a volume segment with volumes V0 from the intermediary mediums by the concerned second entrance of the first recesses arranged in relative to the input and associated for the selection k, into the associated second phase, thus a fluid segment with the volume V0 from the first liquid phase pushes itself to the recess by associated first entrance into the channel; (c) respectively extracting liquid segment with the volume V0; and (d) closing all n second valves and opening all n first valves and bringing out produced fluid stream from the channel; or (p) introducing the fluid stream with the fluid segments into the channel, so that each fluid segment comes to rest before the respective second entrance associated to the well provided for the respective fluid segments, (q) opening of all second valves of all recesses associated for selection k and closing of all first valves of all recesses associated for selection k, (r) conveying of intermediary mediums to an input of the channel, where the respective fluid segment is promoted by respective second phase into the associated second entrance of the first recess arranged in the channel, from where it rises due to the density difference to the intermediary mediums to the respectively first phase, and (s) repeating the steps (r) for all recesses belonging to the selection k; or (p1) introducing the fluid stream with the fluid segments into the channel, so that each fluid segment comes to rest before the respective first entrance associated to the well provided for the respective fluid segments, (q1) opening of all second valves of all recesses associated for selection k and closing of all first valves of all recesses associated for selection k, (r1) conveying of intermediary mediums to an input of the channel, where the respective fluid segment is promoted by respective first entrance into the first phase, and (s1) repeating the steps (r1) for all recesses belonging to the selection k.
