Piston Sampler — Bottom Part

A piston sampler is an auger made from a thin-walled, high-quality stainless-steel tube. It is ideal for sampling moderately cohesive soil layers beneath the water table, to a maximum depth of 5 metres.

The tube's bottom end is fully open; at the top end there are outlets and an opening through which the stainless-steel piston rod passes. A piston is fitted to the bottom of the piston rod, and a wire eye at the top allows a polyester cord to be attached. A bayonet connection at the top of the piston sampler allows it to be attached to the upper part or to extension rods.
