Product description

Geological examinations form the foundations enabling an understanding of the Earth’s composition and changes in it. In addition to rock, seepage water dripping from stalactites below the ceiling of underground caves is of interest, too. The changing composition of the water demonstrates developments, and in tandem with the stalactites, it serves as a climate and environment archive. In order to establish such an archive, water samples are examined regularly and over a longer period. The samples have to stay unaltered until they undergo a laboratory analysis. There are hardly any solutions for automated sampling, so that as a rule, this must be carried out manually. Geologists work their way into the caves together with their equipment and take samples by hand. In these remote and often barely accessible places, long-term, regular sampling is difficult or even impossible. Scientists at the KIT recognised what was needed and developed a robot that independently conducts sampling once it has been adjusted for an operation. Water collected by the robot is filled into water- and airtight test tubes with an automatic catching and injecting device. This protects the samples e.g. from evaporation, gas exchange or contamination. A specially developed needle maintains a pressure balance during injecting. Depending on the respective interval between samples, the sampling vessels are accurately triggered and filled - up to 160 samples per operation. Accommodated in a special suitcase, the sample collector works reliably in damp, dirty environments and has a stand-alone power supply. This enables the system to stay at remote measuring points for longer periods and independently take samples.

You can get an overview of this technology at KIT stand. Detailed information can be exchanged individually in contact with the responsible scientific employees of KIT after the industry fair.
