ABSTRACT:
The improved system of the present invention comprises a hand manipulatable first manifold comprising a hollow housing and a plurality of stubs connected to said housing at spaced intervals, extending outwardly from said housing and defining openings communicating with the interior of the housing. The stubs have at their free outer ends removable suction cups having central openings in communication with the stub openings. This manifold also includes suction means in the form of tubing connected to the hollow handle portion of the housing for providing suction to the housing, and suction-relieving means in the form of a hand-openable closure releasably sealing an opening in the handle. This manifold permits the simultaneous removal of the covers from a plurality of petri dishes or the like culture-containing reservoirs, by means of the suction cups.
A second manifold is provided which also can be hand held and which comprises a hollow housing having a plurality of aspiration conduits connected to the housing at spaced intervals, extending outwardly from the housing and communicating with the interior of the housing. The aspiration conduits terminate in removable pipettes for aspirating culture media from the reservoirs once the covers have been removed by the first manifold. The number of pipettes is equal to the number of suction cups and the spatial arrangement of the pipettes is the same as that of the cups.
