Abstract

In a liquid dispenser (1) for dispensing metered aliquots of a liquid, an inlet (5) is provided for admitting liquid into a chamber (2) of the said liquid dispenser (1) and for permitting egress of air from within the said chamber (2), said inlet (5) being provided with two generally semi-circular or D-section conduits, said conduits being of substantially the same area and a said area being selected such that liquid flowing through a said conduit into said chamber (2) does not cause the formation of air bubbles in any liquid already within the chamber (2). A suitable cross-sectional area for a said generally D-shaped conduit is 15+/-1.5 mm<2>.
