of paper.

be taken because the qTOWER³ cannot be decontaminated as a whole device.

Pay attention to the efficacy spectrum of the listed disinfectants with regard to your cus-
tomer-specific decontamination requirements!
Only the use of ethanol or isopropanol containing disinfection agents is ap-
proved for wipe disinfection. The use of disinfection agents with ingredients or
concentrations that differ from the recommended disinfection agents invalidates
all warranty claims regarding damage to the device or non-effectiveness.
If the qTOWER

has to be sent to Analytik Jena AG for service, a prior decon-
tamination must be carried out and documented (see "Return" p. 41).
