<p>A container for determining antibodies or antigens in a biological liquid by the formation of specific antibody-antigen complexes, in which one partner element is initially associated with suspended magnetic particles that are subsequently regrouped against a certain area of one wall (8) of the container when the container is positioned within a magnetic field that extends through that area of the wall. To prevent the particles from sliding down when the magnetic field is eliminated and to allow effective pipetting, the lower part of said area of the wall is adjacent to a plane surface (7) that is at an obtuse angle to said wall and tangent to a concave surface (5) that is itself tangent to a wall (6) of the container opposite to the wall that is at an obtuse angle. </p> |
