Abstract
An apparatus for sampling and collecting wood samples for analysis purposes which includes a boring bit surrounded by a chamber into which the boring bit draws samples and from which the samples are passed to a collection container. The boring bit is housed in a pair of slidably connected housing members which determine the depth that the boring bit enters a wood sample. Collected samples are analyzed for microbial contaminates.
