Ekman grab, set This grab is intended for use in soft sediment that is free from plant growth. Two thin hinging flaps are open while the grab is lowered. The flaps close when a drop-weight is dropped (cable operated) or a button is pressed (rod operated). Samples can, therefore, also be taken from very soft top layers. The pressure of the sample prevents much loss of material. Nevertheless, small stones or stalks may prevent the grab from closing properly, in which case, the Vrijwit auger (art. no. 04.22) should be used. The grab holds 3.5 litre and the dimensions are 152 x 152 x 152 mm. A rod of 1.5 m in length is also available for the rod-operated use of the Ekman grab in shallow water. Benefits Ekman grab · The flaps overlap on closing to prevent the loss of the sample; Stainless steel construction; · Equipped with drop-weight system so that sampling can be carried out at any depth. Applications · Sampling in soft sediments free from debris and plant growth.
