This invention relates to a device and a method for sampling of milk. The device includes a collecting member (15, 15') arranged to receive milk samples from a milk line (1), which is arranged to transport milk from one animal (3) at a time, and a passage (8a, 12'', 13) arranged to allow a milk flow from the milk line (1) to the collecting member (15, 15'). The device comprises flow means (11, 19) arranged to provide a milk flow, from the animal (3), through at least a part of the passage (8a, 12'', 13) at least a time period before a milk sample is to be taken in order to rinse at least the part of the passage (8a, 12'', 13) from milk residues from a previously milked animal.
