Collect samples at different depths in sediment and wet soils with our Peat or Russian Corer. Designed to take samples below the groundwater level. Once in position the corer is turned so fills and closes with no loss of sediment sample

The sample containing part is a half cylinder. At the correct sampling depth the complete sampler is given half a turn clockwise (180°). During the turning the fin remains in position which allows the half cylinder to be filled and closed again.
