A liquid sample container for use in the examination of liquid by means of visible or invisible light, comprising a body defining therein a recess or chamber for a liquid sample to be examined, said recess or chamber forming part of a first conduit defined in said body which conduit extends substantially vertically in the intended position of use of the container, a second conduit defined in said body substantially parallel to said first conduit, said first and second conduits being interconnected at their bottom ends, a liquid inlet pipe which forms a substantially coaxial continuation of the top end of said second conduit outwardly of said body, a suction pipe which forms a substantially coaxial continuation of the top end of said first conduit outwardly of said body, to enable liquid to be drawn into the said recess or chamber via said inlet pipe and said second conduit, and a substantially straight suction bypass passage interconnecting said first and second conduits and extending substantially at right angles to said conduits, said suction bypass passage being of substantially smaller diameter than the parts of the said conduits which it interconnects and communicating with the respective conduits at a level which is above the said recess or chamber when the container is in its intended position of use.
