Abstract
A sample receptacle including one or more receptacle cavities each having an opening dimensioned such that a liquid within the cavity is retained when the cavity opening is oriented downwardly and/or a gas vent in the base of each cavity sized and positioned to allow gases contained within the cavity to egress whilst preventing the egress of liquid at atmospheric pressure. A sample liquid may be poured into the sample receptacle so that the level of the sample liquid is above each cavity opening and the sample receptacle inverted so as to remove liquid above each cavity whilst retaining sample liquid in each sample receptacle when inverted. This may be used for sample separation or to provide relatively uniform sample volumes to sample wells of a sample container when mated. In another embodiment plungers may be used to eject liquid from receptacle wells via an aperture in the base of each receptacle well.
