THE DES-CONTROLler®: Our DES-CONTROLler® are “closed quadruple indicators“ whose germ carriers (for example Ent. Faecium in different germ concentrations) are covered in a membrane. This eliminates the contamination of the machine that is being checked without impairing the affects of heat and the disinfectant. More decisive is though that the re-contamination of the germ carrier is prevented by the disinfection course and this avoids wrong evaluation results. 4-Fach Indikator
