  • Capillary tube holder for test instruments especially blood tests and particularly for platelet counters, with two coaxial chambers
    Patent number: 4738827
    Abstract: The phial or vial holding for a capillary tube is internally subdivided into an external chamber having annular cross-section and an internal chamber having circular cross-section. The outer wall of the chamber of annular cross-section carries a capillary hole and the inner tubular wall separating the two chambers has a hole in alignment with that of the outer wall and of larger diameter. In the hollow space of annular cross-section, a slight entrained flow through the hole of the inner wall and consequently a fast removal of the sample liquid which has passed through the capillary hole takes place. This is without backward flow in the direction of the capillary hole.
