The apparatus includes sampler head mounted on a handle having an interior bore with a connector for connecting the interior bore to a source of vacuum. The sampler head of the apparatus of the invention includes a collector having a funnel-shaped wall which diverges away from the handle from a minor opening to a major opening. A separator plate is provided having an exterior surface oriented in the direction of divergence of the funnel-shaped wall and with an interior surface in communication with the interior bore of the handle. A cutter holder is mounted on the separator plate and extends into the collector with the cutter holder being generally centered with respect to the minor opening of the collector and the funnel-shaped wall. The apparatus further includes an elongate, removable cutter sleeve which is attachable at an attachment end to the cutter holder.
