  • Particle analysis system
    Patent number: 4607526
    Abstract: A system that is particularly useful in biological fluid analysis includes a face plate member and a mating flexible member, one of which has a plurality of passages. Selected motion of the flexible member provides a valving action to control fluid flow into, through, and out of the passages. An analysis chamber in a surface of the face plate member is in fluid communication with a passage and has an analyzer which, for a hematology analyzer, is preferably an impedance-type particle counter.
