Abstract (en)
[origin: WO9015333A1] New and improved apparatus and method for the self-levelling of a liquid in a container (10) to a precisely predetermined level, with a concave meniscus, are provided and comprise a plurality of ribs (14, 16) defining with the container inner surface (28) one or more capillary pathways formed by the rib-container surface junctures (30, 32, 34, 36) operatively associated with the container (10) and operable upon contact therewith by the liquid within the container (10) to flow liquid out of the container (10) until the liquid has assumed the precisely predetermined level within the container (10) and to provide a concave liquid meniscus at that level. Central support of a predetermined volume of an immiscible isolation liquid on the concave meniscus of the liquid in the container (10) of the precisely determined liquid level is also disclosed.
