Abstract
Devices and methods for handling liquids are provided. The devices and methods make use of specifically controlled centrifugal forces to drive liquid flow between two cavities connected by a conduit such that as liquid flows into the second cavity, a gas volume is trapped in the second cavity and a pressure of the gas increases, allowing for pneumatic control of liquid flow. The devices and methods facilitate one or more of the mixing, metering and sequencing of liquids, for example on a microfluidic device.
