Abstract
A liquid handling device having an axis of rotation about which the device can be rotated to drive liquid flow in the device. The device includes an upstream chamber comprising an outlet, a downstream chamber including a proximal portion radially inwards of a distal portion and including a first port disposed in the distal portion and a first conduit which connects the outlet of the upstream chamber to the first port of the downstream chamber. The first conduit extends radially inwards to a crest and radially outwards from the crest to the first port of the downstream chamber. A distance between the axis of rotation and the crest is greater than or equal to a distance between the axis of rotation and the outlet of the upstream chamber.
