Abstract: A core sampling device includes a core sampling punch, a core excision punch that makes a recess in a receiver body, and an ejector that expels a sample core into the receiver body. The core excision punch is mounted inside the core sampling punch and is substantially coaxial with the core sampling punch. Both punches are able to move in translation and/or rotation with respect to one another, and the ejector is arranged so as to expel cores from each punch.

Abstract: A core sampling device intended to assemble tissue arrays of the type incorporating a core sampling punch, a core excision punch intended to make recesses in one or several so-called receiver blocks, and means to expel the sample cores into one or several paraffin receiver blocks or into any frozen milieu or not, wherein the core excision punch is mounted substantially coaxially in the core sampling punch, the sampling punch being in the external position, both punches being able to move in translation and/or rotation with respect to one another, and the ejection means being arranged to as to expel the cores from each punch.
