DES-controllers of CCD is a simple to use bio indicator for determination and controlling the degree of bacterial reduction.
The DES controller makes it possible to measure the actually achieved degree of bacterial reduction. By applying this method, the influence of temperature and disinfectants are demonstrated and optimal adjustment of the disinfection process is made possible for achieving the objectives established regarding bacterial reduction.
The used indicator-organism is encased in a mechanically, chemically and thermally stable membrane. Micro-organisms can not pass through the membrane, but water and disinfectants can. The membrane makes it impossible to rinse test bacteria during the process of the medium and ensures that all the germs undergo the entire disinfection procedure.
