The Russian Peat Borer (7.5 cm x 60cm model shown) is a side filling chambered-type sampler. This discrete point sampler enables one to drive the sampler to any point in the sediment profile in the closed (empty) position. Once the target depth is reached, the “T” handle is turned clockwise to initiate the sampling while the pivotal cover plate supports the cutting action of the bore. As the sampler is turned 180 degrees, the sharpened edge of the bore longitudinally cuts a semi-cylindrical shaped sample until the opposite side of the cover plate is contacted.
The contained sample can now be recovered without risk of contamination by overlying sediments. The sample is extruded from the bore by a counterclockwise rotation where sample rests on cover plate ready for sectioning.
