Class 5 Ethylene Oxide (Eto) indicator Class 5 Ethylene Oxide (Eto) indicator is the best ways of chemical indicators, The parameters on indicator present us to realize of sterilization process. When we look the indicator, we can understand easily the sterilization process achieve or not. Steam Chemical Indicator Class 4 may be used as internal chemical indicators inside each package, tray, or rigid sterilization container. What do the Class 5 Ethylene Oxide (Eto) indicator mean to the end user ? All Ethylene Oxide cycles must be work using sterilization equipment that has been controled, calibrated and for which IQ and OQ processes have been done. Match equipment status with the relation sterilizer before starting the validation cycles. The parameters for the fractional, half and full cycles must be tested in consultation with the contract sterilizer. During validation cycles, the temperature of the product at several widely matched locations should be monitored and compared with the chamber control temperature. The monitored locations should have somewhere product with B.I. test samples are located. The sterilizer chamber EO concentration and the chamber and product humidity should also be monitored.. Which sterilization process is Class 5 Ethylene Oxide (Eto) indicator designed for ? Class 5 Ethylene Oxide (Eto) indicator strips are designed to be used in EO sterilizers. Which sterilization cycle is Class 5 Ethylene Oxide (Eto) indicator working with ? Before starting the sterilizaiton cycles, consult your sterilizer manufacturer about the relation cycle conditions. What is the standart of ISO for Class 5 Ethylene Oxide (Eto) indicator ? Class 5 Ethylene Oxide (Eto) indicator strips according to ISO 11140-1 standart. CE marking is not applicable for indicator products, because this product is not considered a medical device under the clause of the EC-directive
