A sludge sampler for industrial settling ponds has a handle and an insertion tube of known graduated length so that the sampler may be embedded in sludge at a known depth. At the bottom of the insertion tube is a frame which holds a sampler container jar and which terminates downwardly in a thin walled insertion cone. A lever at the top slides a rod and lifts a cap on the jar so that free flowing sludge may fill the jar. The jar is held in a cage pivoted on the frame. The center of the cover and one edge of the cage are connected by pivoted links. As the cover is lifted, the cage is tipped, tipping the jar to receive the sludge. As the lever is returned to its closed position, the jar-capturing cage is returned to its upright position, the cover is lowered, the jar is covered before the insertion tube is lifted and the cage, the frame , the cone and the jar are lifted out of the sludge.
