ABSTRACT:
Apparatus for drawing a sample of liquid from a body thereof into a sample bottle that has a pierceable resilient sealing closure at one of its ends comprises a support that holds the sample bottle with that end lowermost and at an elevation above the body. Two hollow needles project up from the support to pierce the closure and have their pointed upper ends in the interior of the sample bottle. A shorter one of the two needles is connected with a first duct that extends down to below the surface of liquid in the body; the other needle is communicated with the interior of a sealed wash bottle, near its bottom, which is a little below the support. Another duct, opening from the interior of the wash bottle, near its top, is connectable to a suction source, for drawing liquid through the first duct and the sample bottle into the wash bottle, thus ensuring that liquid remaining in the sample bottle is representative. When that other duct is opened to atmosphere, liquid is siphoned from the wash bottle, through a filled sample bottle, back to the body.
