Abstract
A cartridge for holding a test specimen with an extremely small volume. The cartridge has a test chamber and a vestibule through which the test fluids are inserted into the test chamber. The cartridge has a stopper having a pair of seals, the first of which seals the test chamber inlet between the vestibule and the test chamber, and the second of which seals the mouth of the vestibule so that when the stopper is in place, the test chamber is closed to the admission of air or other contaminants and the vestibule is similarly closed against escape of the overflow from the test chamber.
