Abstract
A multi-well filtration apparatus for the assay of microliter quantities is provided wherein a filter is positioned in each well on a plate having an open spout positioned in the plate. The spout has a collar on its outer surface extending in a direction perpendicular to the vertical axis of the spout. The collar prevents a liquid droplet from climbing the outer surface of the spout from its open end.
