The invention relates to method and an apparatus for vibrating the contents in an aseptic bag (1), in that a device for a regular, varied pressure change is applied on the outer wall side (2) of the bag (1). The pressure change applied on the outside (2) of the bag (1) propagates to the contents of the bag (1) and gives rise to liquid flows in the contents. The device may consist of a diaphragm (4) which abuts against the outside (2) of the bag (1) and moves reciprocally. Alternatively, the device may consist of a bowl (9) which abuts in airtight fashion against the wall (2) of the bag (1). The bowl (9) is connected to a vaccum pump. By varying between vacuum and excess pressure, a pressure change will be obtained against the outside (2) of the bag (1). The bowl (9) may be of such size that a part of the wall (2) of the bag (1) is sucked into the bowl (9) when the bowl (9) is placed under vacuum.
