Document Type and Number:
WIPO Patent Application WO/2016/204638
Kind Code:
A3
Abstract:
A microfluidic device with reduced risk of bubble formation at a capillary junction between two conduits is provided. In some embodiments, the microfluidic device comprises a supply reservoir, a first conduit and a second conduit. The first conduit is configured such that liquid flows by capillary effect from the supply reservoir into the first conduit. The second conduit is connected to the first conduit through an opening in a wall of the first conduit and is configured such that liquid flows from the first conduit to the second conduit by capillary effect. A width of the second conduit, along a direction of liquid flow in the first conduit, is greater than a depth of the second conduit and a depth of the second conduit is less than a depth of the first conduit.
