Apparatus for rupturing a sealed, frangible container is disclosed. A substantially rigid tubular member, closable at both ends if desired, is provided with a zone of reduced interior cross section. The tubular member is adapted to receive the frangible container and retain it in a position so that an annular space of decreasing dimension is formed adjacent the zone of reduced cross section of the tubular member. Means insertable into the annular space wedgedly engage the frangible container with sufficient force to rupture it. |
