Abstract
Microfluidic devices and methods for metering discrete plugs of fluid are provided. The microfluidic devices include a trunk channel and a branch channel having an impedance region. A fluid is supplied to the trunk channel and fills the branch channel to the impedance region. The fluid is then flushed from the trunk channel leaving the branch channel filled. Because the branch channel has a volume, a discrete plug of the fluid having a volume substantially equal to that of the branch channel is formed.
