    Abstract: A metering assembly includes a fluidic chip and metering chambers. Selectable outlet valves communicate with each metering chamber to provide a discrete dispensed volume. The valves may be commonly controlled and may be formed as multi-level valves. The valves may be grouped into common substrate valve clusters. Purge channels communicate with the metering chambers and controlled purge valves allow reverse flow wash fluid to wash the metering chamber. Pressure ports are employed to actuate the valves. A method of dispensing a fluid from the fluidic chip includes a) selectively filling (or filling) the metering chambers with a selected fluid; and b) outputting (or selectively outputting) the fluid to output locations. The total output volume of fluid dispensed from each metering chamber may be accumulated. The process may be repeated until the accumulated volume equals the desired volume and may be repeated for another fluid from a plurality of different fluids.

    Abstract: Pumping systems for pumping shear-sensitive fluids between first and second reservoirs. In various embodiments, the pumping system may include a portable platform that supports at least one diaphragm pump thereon. The diaphragm pumps are arranged for fluid communication with first and second reservoirs. Valve arrangements may be provided that enable the shear-sensitive fluid to be pumped from a first reservoir to a second reservoir. In some embodiments, the valve arrangements enable the user to reverse the flow direction to enable the fluid to be pumped back out of the second reservoir into the first reservoir if too much fluid was initially transferred into the second reservoir. Other embodiments may employ a hand activated nozzle to discharge the pumped fluid.

    Abstract: A fluid displacement mechanism is disclosed. In an embodiment, first and second cavities are separated by a flexible membrane. The first cavity contains a non-conductive fluid and the second cavity contains a conductive fluid. First and second electrodes are positioned in the first and second cavities respectively such that the application of a voltage between the electrodes causes movement of the membrane by the build up of an electrostatic charge between the membrane and first electrode.
