Abstract
A liquid control system for a diagnostic cartridge that is insertable into an analytical instrument, which has a liquid control region located at a border between interior and exterior surfaces of the cartridge when the cartridge is inserted into a slot in the analytical instrument, wherein the region is adapted to fit with an edge formed by exterior surfaces of the analytical instrument and the slot, thereby providing a capillary gap at the edge having a gap width smaller than any gap width of any space contiguous to the gap in the interior of the slot when the cartridge is inserted in the instrument.
