<p>The invention relates to a siphon 10 for siphoning liquid 11 from a storage container 12 to another 13. The siphon comprises a flow duct 14 for a liquid and a plug 16 which is arranged to move in sealing contact within the flow duct. The siphon further comprises means such as a tether 15 for causing the plug to move along the flow duct to draw liquid along the duct and thus transfer liquid from the one container to the other. The tether is preferably threaded through the duct and each end of the tether is connected to the plug in such a way that the tether forms a loop. The plug may comprise a pair of seals (20 figure 2). A later embodiment relates to a method of siphoning liquid comprising the above siphon.</p> |
