full_question: Electroosmotic flow occurs during a form of electrophoresis named for these objects. The length scale at which a drop of liquid begins to flatten due to gravity is named for this object. The time needed for a liquid to flow between two points in one of them is used in certain forms of viscometry . An analyte is placed in one of them before being heated in a MEL-TEMP device to determine melting point. Due to the shape of these objects, surface tension and adhesive forces cause a namesake effect to form a meniscus. These items name an effect in which liquids may flow into them opposing the force of gravity, which is their namesake "action." For 10 points, name these extremely narrow tubes which share their name with very thin blood vessels.
