摘要：
Apparatus for the detection of contaminants in fluids. In the simplest embodiment, the apparatus comprises a vacuum tube having indicator means disposed therein for the detection of a fluid-borne contaminant and a self-sealing, cannula-penetrable closure. The apparatus is operated by piercing the closure with a cannula to draw the fluid for testing into the vacuum chamber.
