Abstract
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 collecting area of a first side wall of the container when the container is positioned within a magnetic field that extends through that area of the side wall. To prevent the particles from sliding down when the magnetic field is eliminated and to allow effective pipetting, the lower part of the side wall is adjacent to a planar surface formed at an obtuse angle to said side wall and tangent to a concave bottom surface that is itself tangent to a second side wall of the container located opposite to the first side wall.
