Abstract
Apparatus for sampling a material in a container both in a laboratory environment and in a field environment is shown. The apparatus includes a portable pump for generating either a partial pressure with respect to atmosphere or a partial vacuum with respect to atmosphere. The partial vacuum is used to force the material from the container through a collection tube into a specimen bottle. When the material in the container is too viscous to be directly drawn into the specimen bottle, a pressure is applied to one end of the collection tube and the material in the collection tube is driven into the specimen bottle. The footpump is modified to provide both a pressure and a vacuum nozzle and is easily portable to a remote location site.
