Abstract

In an ampoule for a medicament the space accommodating the medicament is defined by an ampoule wall (1) a pierceable seal (5) closing one end of the ampoule and a piston (7) closing the other end of the ampoule. A metal containing fixation element (8) is secured to one of the parts defining the medicament accommodating space. A mixing element (9, 10) also containing a metal and having a density larger than 1,0 g/cm<3> is movable in medicament accommodating space. At least one of the elements, the fixation element (8) and the mixing element (9, 10), can be attracted by a magnet, and at least one of these elements is a magnetic element, the magnetic strength being so that the mixing element (9, 10) can during normal handling of the ampoule be fixed relative to this ampoule by the magnetic attraction between the fixation element (8) and the mixing element (9, 10) but may be released from its fixed position by manual operation.
