Sampling case for aquatic organisms

The chemical and physical examination of bodies of water provides important information on their momentary condition.
To obtain information on the long-term changes in a body of water, however, it is necessary to undertake a biological analysis as well. An investigation based on certain "indicator organisms" is highly suitable for determining the long-term, general condition of a body of water.
The sampling case for aquatic organisms contains equipment for four groups, making it possible to take samples of water and examine them for the presence of organisms and to store the samples and the organisms they contain.
