Dormer Piston Sampler

The Piston Sampler is suitable for sampling less cohesive soil layers (sand) below the groundwater table. The piston sampler is also suitable for sampling sediments with a sand content.


The Piston Sampler is used to take undisturbed samples from water-saturated soils like marine mud & silty sand. It operates on the same principle as the fisherman’s bait pump. That is, you push down on the outer tube simultaneously as you pull up on the piston. The piston is held in position while the tube is removed from the hole.
