Реферат: The invention relates to an adapter (1), a device and a method for sampling materials from bag chambers (28a, 28b) pertaining to a multichamber tubular bag (10), wherein materials taken from said chambers (28a, 28b) are led through an adapter (1) and fed separately into separate channels (11a, 11b). Substances can thereby be sampled in a desired amount in certain relative proportions from the chambers of the multichamber bag, thereby dispensing with the need for forced mixing.
