Biological tests are often in the foreground as well as the usual physicalchemical measuring methods. In order to determine the biodegradability of foodstuffs, pollutants, harmful substances or waste substances and the microbial activity so-called respiration (depletion) measurements are often carried out. In these measurements the respiration of the organisms is determined under defined conditions as the oxygen uptake or release of carbon dioxide.
Measurements are carried out via closed systems using the OxiTop®-C in combination with the OC 110 controller. Depending on the field of use, specially adapted measuring vessels, which are all equipped with the necessary connection thread and some of which are autoclavable, come into operation. For this task there are various complete packages available which come equipped with all required utensils.
For the incubation of larger measuring vessels, WTW offers the TS 1006-i thermostatcabinet as well as the IS 6-VAR stirrer platform, which has been specially designed for vessels with large base diameter.
