Device for filling containers with a liquid, in particular for bottling comprising: (a) a filling unit comprising connections connected to a source of the liquid, a source of an inert gas and a suction device; a pipe which comprises (a2.1) a first tube and (a2.2) a second tube, wherein the first tube is arranged as central tube essentially coaxially inside said second tube creating between said first tube and said second tube a corresponding interstice or wherein said first and said second tube extend separately from each other, for example in parallel; and retaining means to hold said containers in the filling unit; (b) elevating means to vary the depth with which said pipe and/or at least one of said tubes (4a, 4b) is inserted in said container; and (c) optionally conveyor means suitable to support and have said containers advance in succession to said filling unit, characterized in that (i) one of said two tubes (4a, 4b) is connected to the connection connected to said source of the liquid and the other tube (4a, 4b) to the connection connected to said source of an inert gas wherein, preferably the first and the second tube can be raised or lowered independently from each other; and in that (ii) is foreseen a space, in particular a channel, for applying the vacuum, preferably arranged in a position which permits the application of the vacuum in the upper part of the container..
