before each usage. The solution Cidex
®
OPA is ready for use and does not need to be diluted.
Test strips to verify that the appropriate concentration of Cidex

contact time is 5 minutes. If a differing disinfectant is used follow the manufacturer’s instructions.
Please also consider the material compatibility for the medical device.
2) Wipe the non-submergible parts of the probe with a soft and fluff free cloth with disinfectant.
3) Immerge the submergible part of the probe (see figure) into the disinfectant. Set a clock to insure the
recommended contact time is observed.
4) Rinse the submergible part of the probe with running deionized water for 1 minute.
5) Alternatively to step 4 suspend the submergible part of the probe in a tray filled with deionized water
for 5 min.
