1. An integral capillary microcuvette comprising a body member having an outer peripheral edge, the body member being provided with a cavity that communicates with the outer peripheral edge of the body member, the cavity being defined by two opposing inner surfaces of the body member, a portion of the cavity defining a measuring zone within the body member, the cavity having an inner peripheral zone at which is located a channel, the channel extending along the entire inner peripheral zone of the cavity, the channel being sized relative to the measuring zone such that the channel has a higher capillary force than the measuring zone to prevent air bubbles from becoming trapped in the measuring zone, the outer peripheral edge of the body member being provided with a sample inlet through which a sample is drawn into the body member, the sample inlet being in communication with the channel and the channel being in communication with the measuring zone.
