Abstract
A device for moving a fluid in a fluidics system. The device may include one or more controllably openable closed chambers. The pressure within the closed chamber(s) is lower than the ambient pressure outside the fluidics system or lower than the pressure within another channel of the fluidic system. The closed chamber(s) is configured for being controllably opened. The chamber (or chambers) is configured such that when a chamber is opened the chamber is in fluidic communication with a flow channel included within the fluidics system. The fluid may be moved into the flow channel or may be moved within the flow channel. The fluid may be a liquid, a gas, a mixture of gases or an aerosol. The fluidics system may include a controller for controlling the opening of a selected chamber or chambers.
