    摘要： Improved microfluidic devices, systems, and methods allow selective transportation of fluids within microfluidic channels of a microfluidic network by applying, controlling, and varying pressures at a plurality of reservoirs. Modeling the microfluidic network as a series of nodes connected together by channel segments and determining the flow resistance characteristics of the channel segments may allow calculation of fluid flows through the channel segments resulting from a given pressure configuration at the reservoirs. To effect a desired flow within a particular channel or series of channels, reservoir pressures may be identified using the network model. Viscometers or other flow sensors may measure flow characteristics within the channels, and the measured flow characteristics can be used to calculate pressures to generate a desired flow. Multi-reservoir pressure modulator and pressure controller systems can optionally be used in conjunction with electrokinetic or other fluid transport mechanisms.

    摘要： This invention is a debubbler, degasser or gasser device used to remove gas bubbles and/or dissolved gasses from a liquid stream or to add gasses to a liquid stream. The device consists of a first block, a hydrophobic membrane, and a second block. The first block has a channel for carrying liquids which is grooved into its lower surface. The end of the channel is connected to an inlet and outlet. The second block has venting holes. When the hydrophobic membrane is pressed between the first and second block liquid can flow through the channel and bubbles or dissolved gasses in the liquid stream pass through the hydrophobic membrane. Alternatively, or in combination with degassing or debubbling, the device may be employed to introduce into the liquid stream gasses provided on the opposing side of the hydrophobic membrane.
