Cleaning and disinfection

Forcleaning,immersethelightprobeinacleaningsolu-

tionandensurethatitissufficientlycoveredwithliquid

(ultrasoundorcarefulbrushingwithasoftbrushmay

supporttheeffect).Aneutral-enzymaticcleaningagentis

recommended.Whencleaninganddisinfecting,please

makesurethattheagentsusedarefreeof:

–organic,mineralandoxidizingacids(theminimum

admissiblepHvalueis5.5)

–alkalinesolution(themaximumadmissiblepHvalue

is8.5)

–oxidizingagent(e.g.hydrogenperoxide)

Afterwards,removethelightprobefromthesolutionand

thoroughlyrinseitunderrunningwater(foratleast

10seconds).Cleaninginathermaldisinfectorisaneffec-
