<p>A manually operated apparatus for attaching one or more pump mechanisms (38) to a like number of sealed test tubes (26), each test tube sealed by a resilient, puncturable closure (28). The apparatus includes a frame (10) having a base (12), a support (34) attached to the frame (10) for releasably supporting one or more pump mechanisms (38), a test tube holder (20) for releasably holding one or more test tubes (26), the holder (20) movably engaging and being displaceable on the base of the frame (10) into position in alignment with the support (34), and a manually operated insertion mechanism (54), attached to the frame (10), for displacing the support (34) towards the holder (20) (with test tubes (26) therein), to puncture the closure (28) of a test tube (26) with a pump mechanism (38). Using the apparatus includes placing one or more test tubes (26) having closures (28) into the holder (20), displacing the holder (20) into position, placing one or more pump mechanisms (38) in the support (34), and manually activating the insertion mechanism (54) to puncture the one or more closures (28) with the one or more pump mechanisms (38). <IMAGE></p> |
