This manually-driven, side-filling sampler collects discrete, uncompressed samples from rivers, lakes, wetlands, and estuaries. The single-moving part, chambered-type borer collects quality samples which are not compressed or shortened during recovery, unlike samples taken with end-filling core samplers. Sampling is easy. Simply deploy the borer (in the closed position) to the desired depth. The bore is rotated clockwise 180° so that the sharpened edge of the chamber cuts a semi-cylindrical sediment core which is contained by the pivotal cover plate. During retrieval, the cover plate’s counterclockwise rotation extrudes the undisturbed sample. Ideal for use in woody peat, sand, silt, and clay. Borer measures 5 cm in diameter and 50 cm in length with a sample volume of 10 ml/cm. The optional bronze slide hammer assembly (sold separately) helps you drive and retrieve the borer in compact deposits. Use the lightweight, buoyant aluminum holobar extension rods for one-man operation of the sampler from a boat. Additional rods (4.0 cm diameter) are available in two lengths, 1.2 m and 2.4 m. Borer includes stainless steel borer head, two 1.2 m aluminum holobar extension rods, turning handle, carrying case, and reference materials.
