ABSTRACT New and improved apparatus and method for the self-levelling of a liquid in a container to a precisely predetermined level, with a concave meniscus, are provided; and comprise one or more capillary pathways operatively associated with the container and operable upon contact therewith by the liquid within the container to flow liquid out of the container until the liquid has assumed the precisely predetermined level within the container, and to provide a concave liquid meniscus at that level. New and improved apparatus and method are also provided to transfer completely bubble-free liquid from a liquid supply chamber to a container; and comprise one or more capillary pathways operatively associated with both the supply chamber and the container and operable upon contact therewith by the liquid in the supply chamber to flow completely bubble-free liquid therefrom into the container, which may also include the self-levelling means as heretofore described. Central support of a predetermined volume of an immiscible isolation liquid on the concave meniscus of the liquid in the container of the precisely predetermined liquid level is also disclosed.
