Disclosed is a closure (10) for a container including: (a) an inner cylindrical wall (11) defining a space: (b) an outer cylindrical wall (12), opposite the inner cylindrical wall forming an outer surface of the closure: (c) a first end wall (15), wherein said first end wall comprises a recess (16) extending a least partially into said space, and a first set of threads (18) disposed on said recess. In a preferred embodiment, a second set of threads is disposed on said inner or outer cylindrical wall (11,12) having a direction which is opposite that of the first set of threads (18). Moreover, the disclosure comprises an apparatus which removes and installs said closure (10) on a container and includes: a threaded rotatable spindle (50) adapted for threading into said threaded depression of the closure and for applying a rotational force to remove the closure; and a clutch (30) having an element adapted to engage the closure and apply a rotational force to the closure. The apparatus can be used on an analyzer, such as a diagnostic analyzer. |
