The Macro-Core® Soil Sampler collects samples in consolidated materials, including soils, sediments, and waste materials or a mixture of these. This sampling device works well in medium- to fine-grained cohesive materials such as silty clay soils or sediments.
A piston point is held inside the cutting shoe by a piston rod. The piston rod extends up through the sampler into the drive head. A stop-pin threaded into the drive head holds the piston rod in place thus holding the piston point in place.
Once the sampler has been advanced to the top of the sampling interval, the stop pin is released via extension rods. The stop-pin and piston rod are removed from the sampler by retracting the extension rods.
The sampler is now advanced through the sampling interval. As soil enters the sampler, the piston point is displaced upward into the sample tube. When the sampler is retracted from the probe hold and disassembled, the piston point can be removed from the top of the soil core. The sampler is disassembled in seconds, decontaminated, and the whole process can be repeated in a matter of minutes.
