ABSTRACT:
A fluid sampling apparatus for taking samples of fluid from predetermined depths in a body of water comprises a receptacle for releasably holding therein a sample collection bottle. A single suspension means such as a rope is provided, by means of which the assembly can be raised and lowered. Attached to the bottom of the suspension means is an interference fit stopper such as a cork and a resilient engaging means, for releasably engaging ribs on the neck of a bottle disposed within the receptacle. As the assembly is lowered by means of the suspension means, it is suspended by means of the resilient releasable means engaging against ribs on the bottle neck. When it has been lowered to the required depth, the suspension means is jerked suddenly upwardly, causing the resilient releasable means to release the bottle, with consequent removal of the stopper to permit filling of the bottle. After freeing from the bottle, the resilient engaging means abuts against the top wall of the container, allowing the assembly to be withdrawn upwardly by means of the suspension means.
