ABSTRACT:
An improved sampler is enclosed. In the preferred and illustrated embodiment, the sampler comprises a compressable sample collection head formed of a resilient material having a dished area therein which head is pushed by a push rod against a mating or facing surface of harder material. The collection head is encased in a shield. The improved apparatus includes a projecting mounting post extending into the collection head and which is bonded thereto, further including an undercut portion having an enlarged overhanging shoulder to secure the collection head. This prevents separation of the collection head from the push rod.
