Webster Dictionary

  1. Siphonnoun

    a device, consisting of a pipe or tube bent so as to form two branches or legs of unequal length, by which a liquid can be transferred to a lower level, as from one vessel to another, over an intermediate elevation, by the action of the pressure of the atmosphere in forcing the liquid up the shorter branch of the pipe immersed in it, while the continued excess of weight of the liquid in the longer branch (when once filled) causes a continuous flow. The flow takes place only when the discharging extremity of the pipe ia lower than the higher liquid surface, and when no part of the pipe is higher above the surface than the same liquid will rise by atmospheric pressure; that is, about 33 feet for water, and 30 inches for mercury, near the sea level

    Etymology: [F. siphon, L. sipho, -onis, fr. Gr. a siphon, tube, pipe.]

  2. Siphonnoun

    one of the tubes or folds of the mantle border of a bivalve or gastropod mollusk by which water is conducted into the gill cavity. See Illust. under Mya, and Lamellibranchiata

    Etymology: [F. siphon, L. sipho, -onis, fr. Gr. a siphon, tube, pipe.]

  3. Siphonnoun

    the anterior prolongation of the margin of any gastropod shell for the protection of the soft siphon

    Etymology: [F. siphon, L. sipho, -onis, fr. Gr. a siphon, tube, pipe.]

  4. Siphonnoun

    the tubular organ through which water is ejected from the gill cavity of a cephaloid. It serves as a locomotive organ, by guiding and confining the jet of water. Called also siphuncle. See Illust. under Loligo, and Dibranchiata

    Etymology: [F. siphon, L. sipho, -onis, fr. Gr. a siphon, tube, pipe.]

  5. Siphonnoun

    the siphuncle of a cephalopod shell

    Etymology: [F. siphon, L. sipho, -onis, fr. Gr. a siphon, tube, pipe.]

  6. Siphonnoun

    Etymology: [F. siphon, L. sipho, -onis, fr. Gr. a siphon, tube, pipe.]

  7. Siphonnoun

    a sproutlike prolongation in front of the mouth of many gephyreans

    Etymology: [F. siphon, L. sipho, -onis, fr. Gr. a siphon, tube, pipe.]

  8. Siphonnoun

    a tubular organ connected both with the esophagus and the intestine of certain sea urchins and annelids

  9. Siphonnoun

    a siphon bottle

    Etymology: [F. siphon, L. sipho, -onis, fr. Gr. a siphon, tube, pipe.]

  10. Siphonverb

    to convey, or draw off, by means of a siphon, as a liquid from one vessel to another at a lower level

    Etymology: [F. siphon, L. sipho, -onis, fr. Gr. a siphon, tube, pipe.]


  1. Siphon

    The word siphon is sometimes used to refer to a wide variety of devices that involve the flow of liquids through tubes – see siphon terminology – but in the narrower sense it refers specifically to a tube in an inverted U shape which causes a liquid to flow uphill, above the surface of the reservoir, without pumps, powered by the fall of the liquid as it flows down the tube under the pull of gravity, and is discharged at a level lower than the surface of the reservoir it came from. Note that while the siphon must touch the liquid in the reservoir, it need not touch the liquid in the lower reservoir and indeed there need not be a lower reservoir – liquid can discharge into mid-air. In practical siphons, atmospheric pressure pushes the liquid up the tube into the region of reduced pressure at the top of the tube in the same way as a barometer, and indeed the maximum height of a siphon is the same as the height of a barometer, because they operate by the same mechanism. The reduced pressure is caused by liquid falling on the exit side. When both ends of a siphon are at atmospheric pressure, liquid flows from high to low. However, if the lower end is pressurized, liquid can flow from low to high, as in siphon coffee. While in everyday siphons, atmospheric pressure is the driving mechanism, in specialized circumstances other mechanisms can work – in the laboratory, some siphons have been demonstrated to work in a vacuum – see vacuum siphons – indicating the tensile strength of the liquid is contributing to the operation of siphons at very low pressures. Most familiar siphons have water as a fluid, though mercury is often used in experiments, and other fluids such as organic liquids or even carbon dioxide can be siphoned.
