Fields of Application
For the automated chemothermal reprocessing of flexible endoscopes in AERs.
thermosept® PAA base/additive is suitable for the use in all common AER systems which are released for the use of peracetic based products.
Microbiological efficacy: Bactericidal, tuberculocidal, mycobactericidal, levurocidal,
virucidal (in accordance with DVV/ RKI Guideline 12/2014 and EN 14476), sporicidal (Clostridium difficile spores) at 1.2 % - 35 °C - 37 °C - 5 minutes.
Instructions for use
Whenever possible, simultaneously dose 1.0 % - 1.2 % (10 - 12 ml/l) of thermosept® base and 1.0 - 1.2 % (10 - 12 ml/l) of thermosept® additive. At temperature of 35 °C dosage of 1,2 % is needed. If the AER metering pumps are unable to dose the two components simultaneously, add 1.0 % - 1.2 % of thermosept® PAA base and then thermosept® PAA additive immediately thereafter. Ensure that this order is followed so as to guarantee material compatibility. The contact time is 5 minutes at 35 °C - 37 °C.
Disinfection components are compatible with the mild alkaline cleaning agend thermosept® EndoCleaner. Approved microbiological compatibilty.

Special advice
The base and additive components have to be used in combination. Store in original container at room temperature. Keep the container tightly closed. Protect from heat and sunlight. thermosept® PAA is not suitable for instruments made of brass and copper or chrome-plated instruments. According to EN 17664, the instrument manufacturers' instructions should be followed and, if necessary, the compatibility of the materials ensured before the application. This applies in particular when reprocessing older endoscopes. These should be strictly tested for compatibility with peracetic acid. For professional use only. Read label and use instructions before use.
