Method for sealing a chamber to prevent air entrapment in a lu00ecquido test.Sealing system for sealing a test chamber to prevent air entrapment in lu00ecquido inserted to the inside of the chamber, and,The cartridge which contains a test chamber for use in apparatus for performing optical analysis of specimens of lu00ecquido through observation of optics.A cartridge (21) to hold a specimen of test with a volume is extremely small.The cartridge has a test chamber (63), and a vestibule (66) through which fluids are inserted to the inside of the test chamber test.The cartridge has a stop (60) which has a pair of seals (72, 74), the first of which seals the test chamber inlet (65) between the vestibule and the test chamber, and the second of which seals.The mouth (67) of the porch, so that when the door is in place, the test chamber is closed to the admission of air and other contaminants.And the vestibule is closed in a similar manner against leakage and overflow from the test chamber.
