A dual channel needle is inserted into the container and a dissolving solution is injected into the ampoule to form a solution. A rinsing solution is circulated into the interior of the apparatus to remove that solution which is then directed to means for culturing and incubating a filtrate of the solution to determine whether microorganisms are present therein. The needle is retained by hand into the ampoule and held by the cap of the closed transfer chamber during rinsing.
