Manual disinfection:
1) Prepare the disinfectant solution in a tank with cold water (please
follow the instructions of the disinfectant manufacturer regarding
application, concentration, microbiological efficiency, service life
and contact time).
2) Confirm the concentration of the disinfectant before immersing the
probe. Although Cidex® OPA does not need to be diluted, it is recommended
to use test strips to verify the concentration. The test strips can
indicate whether or not the concentration is above the Minimum
Effective Concentration (MEC). Please also note the expiration date
of the test stripes. Temperature of disinfectant solution should be
minimum 20°C. The minimum contact time is 5 minutes. If a different
disinfectant is used, follow the manufacturer's instructions. Please
also consider the material compatibility for the medical device.
3) Immerse the immersible part of the probe into the disinfectant (see
Fig. 4). Set a clock to insure the recommended contact time which
is 5 minutes.
4) Rinse the immersible part of the probe with deionized water for 1
minute. (alternatively: immerse the immersible part of the probe in
a tray filled with deionized water (see Fig. 4) for 5 min.)
5) Visually check the outer surface of the probe for leavings of the
disinfectant. If necessary, repeat the rinsing.
