ABSTRACT:
A Kemmerer style water sampler has a tubular body open at both ends and through which a connecting rod extends. One end of the connecting rod is fixed to a lower closure and has a latch mechanism at its other end coupled to an upper closure. The latch mechanism is releasable by means of an actuator which is movable in response to the application thereon of a tensile force in a direction to release the latch and enable the closures to move to body sealing positions. The tensile force may be applied on the actuator in virtually any position of the tubular body.
