This application note provides information on specific application methods and the use of Hettich products.


Escherichia coli (E. coli) is a bacterium that is present in the body of both animals and humans. It is part of the normal healthy intestinal flora. However, if E. coli bacteria are ingested through food or water or come into contact with mucosa, then infections may result and can lead to sepsis. If the bacteria have undergone mutation, they can cause life-threatening diseases (e.g. EHEC) through highly toxic metabolic products.

E. coli plays an important role as an indicator organism in water analysis. If its presence is demonstrated, then it can be assumed that the water sample is contaminated with other fecal organisms. Drinking water must be absolutely free of E. coli, i.e. no organisms present in 100 ml.
