摘要： A device configured for rotation about an axis of rotation to drive liquid flow within the device. The device includes a detection chamber having opposed first second ends and two optical features defining an optical path through the detection chamber, between the first and second ends. The detection chamber includes a first liquid inlet disposed at the first end on a first side of the optical path, a first liquid outlet disposed at the second end of the detection chamber on the first side of the optical path and a second liquid outlet disposed at the second end of the detection chamber on a second side of the optical path. The first side of the optical path is radially outwards of the second side of the optical path.

摘要： 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 having 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.

摘要： A liquid handling device having an axis of rotation about which the device can be rotated to drive liquid flow. The device includes a vented upstream chamber having an outlet port and an unvented chamber including an inlet port to receive liquid from the outlet port of the upstream chamber and an outlet port radially outward the inlet port. The device further includes a vented downstream chamber having an inlet port to receive liquid from the outlet port of the unvented chamber. A downstream conduit connects the outlet port of the unvented chamber to the inlet port of the downstream chamber and includes a bend radially inward of the outlet port of the unvented chamber. An upstream conduit connects the outlet port of the upstream chamber to the inlet port of the unvented chamber.
