Abstract
A method and a system are disclosed for filling a straw which is fitted with a stopper that is permeable to gases and impermeable to liquids and which has a diameter greater than or equal to approximately three millimeters with a liquid while it is vertical. A primary vacuum is established in the straw. The straw is then filled and a quantity of air remaining above the resulting column of liquid is evacuated, enabling homogeneous filling of the straw.
