    摘要: Disclosed herein is a device for measuring fluid dispense volumes including one or more wells adapted to receive a fluid; a tube having an internal passageway fluidly coupled to the one or more wells, wherein fluid in the wells passes into the internal passageway via capillary action to form a fluid column having a meniscus spaced from the wells; and a scale coupled to the tube, the scale calibrated to provide an indication of the volume of the fluid based upon the location of the meniscus in the fluid passageway.

    摘要: Devices and methods for performing separation of cell particles by dielectrophoresis in three dimensions. In one embodiment the device comprises a flow chamber having microfabricated chip with a plurality of vertical and horizontal electrodes, which may be coated with a protective layer to prevent direct contact between any electrode and a sample. The horizontal electrodes are in electrical communication with a DC or an AC power source, while the vertical electrodes are in electrical communication with an AC power source.
