Ekman-Burge dredger
Ekman-Burge dredger Sampling is the first and one of the most important stages of chemical, microbiological and other types of analysis. The reliability of the results of subsequent measurements depends on its implementation. Errors resulting from incorrect sampling are almost impossible to correct in the future. As a result, further research, even using the most accurate and expensive equipment, may be pointless. That is why great attention is paid to correct sample selection. The most important factors influencing the correct sampling are the training of specialists performing sampling and the use of special equipment that makes sampling accurate, reproducible and eliminates contamination from the outside. The Ekman-Burge dredge is designed for quantitative recording of macro and microbenthos. Description The dredge slowly sinks in the open state. The mechanism is activated when the device touches the bottom of the reservoir. The cable system ensures that the doors close with 5 times the force. Benefits Mechanized sample unloading facilitates the work of opening the bottom grab valves. Additional weights to increase the penetrating ability of the device. Possibility of adding up to 50 weights of 1 kg. The device is successfully operated in departments of Roshydromet, TsLATI, water management agencies, laboratories of universities and research institutes.
