Abstract
A container for containing a liquid for use in a biochemical analysis includes a cylindrical inner side wall, a bottom wall connected to the inner side wall at its lower end and a cylindrical outer side wall surrounding concentrically the inner side wall and being separated from the inner side wall to form a ring-shaped recess therebetween. Even if the liquid overflows beyond the inner side wall, an outer surface of the outer side wall is kept free from the liquid and the operator's fingers are protected against contamination by the liquid.
