An arrangement for sampling a liquid by a closed procedure which includes penetrating the closure (34) of a container (33) of liquid by a needle (62) having a bore (68), a solid point (63), and a radial passage (66) near the point of communication with the bore, the needle including a space (67) ext

An arrangement for sampling a liquid by a closed procedure which includes penetrating the closure (34) of a container (33) of liquid by a needle (62) having a bore (68), a solid point (63), and a radial passage (66) near the point of communication with the bore, the needle including a space (67) extending coaxially therein in addition to the bore, and outward apertures (70) and (71) communicating with the space and positioned so that when the needle penetrates the closure into the container for a predetermined distance, one of the apertures is within the container and another of the apertures is outside the container.

The method of extracting a sample from a container of fluid having a longitudinal axis and a penetrable, self-sealing enclosure at one end, comprising the steps of: (1) mounting said container with said axis vertical and said closure upward, (2) actuating a hollow needle having a plurality interconnected apertures and passageways therein, axially penetrate said closure and enter said container, (3) draining contents from said container through needle while simultaneously admitting replacement air to said container, (4) withdrawing said needle from said container into a substantially enclosed area while wiping any contents from the surface of said needle as it is being withdrawn, (5) passing a cleaning liquid through a portion of said apertures and passageways of said hollow needle while preventing said cleaning liquid from having any contact with said container, and (6) removing said cleaning fluid from said needle without exposing said fluid to the ambient atmosphere surrounding said container and said needle.
