    摘要： To ejecting a droplet from a reservoir, the reservoir holding a fluid is moved with respect to an acoustic ejector. As the reservoir and ejector move closer together, the acoustic ejector sends one or more interrogation pulses towards the reservoir. Based on the interrogation pulses, the system determines when the movement of the reservoir has placed a free surface of the fluid in a position where a droplet can be ejected.

    摘要： A method of determining the volume or height of fluid in a reservoir is provided. A first burst of focused acoustic energy is used to raise temporarily a protuberance on a free surface of the fluid. A second burst of acoustic energy is directed to the free surface of the fluid. Echoes from the second burst of acoustic energy are detected. The detected echoes are employed to compute the height of the fluid.

    摘要： Fluid containers are disclosed which have fluid reservoirs in their closures. These reservoirs are advantageous to hold sacrificial fluid which lessens the loss of the fluid of interest to the outside through evaporation. The reservoirs may have openings to the inside or outside of the container, or to both. Reservoirs with openings to the outside serve to reduce evaporative loss by raising the partial pressure of fluid in the vicinity of the contact between the closure and the remainder of the container. The reservoirs may be refillable without opening the container. In one embodiment a fluid reservoir allows the zone of contact between the closure and the remainder of the container to be immersed in fluid, so that gases seeking to escape the interior of the container must pass through fluid.

    摘要： Devices and methods are provided for reducing the uncontrolled electrostatic charges that can alter the volume and/or trajectory of a droplet, which is typically ejected through the application of focused acoustic radiation. Also provided are reservoirs and substrates, e.g., well plates formed from a material that is at least partially nonmetallic or polymeric and either has an electrical resistivity of no more than about 1011 ohm-cm, has a surface electrical resistivity of no more than about 1012 ohm/sq, or both.
