    摘要: Bubble-free electrodes, electrochemical cells including bubble-free electrodes, analytical devices, and methods for preparing and using them are provided. The analytical devices each include at least one bubble-free electrode. Analytical devices that include an electrochemical cell and a sample containment device are also provided, wherein the electrochemical cell includes an anodic reservoir, a cathodic reservoir, an electrical connection between the anodic reservoir and the cathodic reservoir, and a first bubble-free electrode disposed within one of the anodic reservoir and the cathodic reservoir. A second electrode is disposed within the other reservoir and a power source is provided having a positive terminal that is normally in electrical contact with the first electrode, and a negative terminal that is normally in electrical contact with the second electrode. The analytical device further includes a power source polarity-inverting device for switching the contacts between the terminals of the power source and the first and second electrodes. The sample containment device includes a sample containment chamber having an opening for introducing a sample into the chamber and being positioned with respect to the electrochemical cell such that an electrical field generated by the electrochemical cell can influence a property of a component of a sample disposed in the sample containment chamber. Pressure-generating cells are also provided.

    摘要: The present invention provides, in one aspect, an apparatus that comprises a disc-shaped substrate defining (1) a central reservoir region, (2) a plurality of channels in fluid communication with, and emanating substantially radially from, the central reservoir region, the channels being coplanar with each other, and each channel having (i) a proximal end which is linked to the reservoir region, and (ii) a distal end, and preferably (3) for each channel, at least one chamber, and preferably three chambers, linked by a passageway in fluid communication with the distal end of that channel. Preferably, each passageway leads from each chamber in a direction that is initially away from the central reservoir region, whereby centrifugation of the substrate about a central axis that is perpendicular to the channels is effective to disperse liquid from the central reservoir region into the channels and chambers, such that any air bubbles in the chambers, channels, and passageways are forced towards the axis of rotation, when such liquid is present in the central reservoir region.
