Memmert GmbH + Co.KG dry heat sterilizers type S do perform dry heat sterilization cycles for any other kind of medical item. Respirators or mask can be sterilized using Memmert sterilizers type S as long as: ► the materials the respirators are composed of are compatible to the applied sterilization process parameters, i.e. are compatible to the temperature over time. ► the bioburden of the respirators are established. ► the applied sterilization process is validated, mainly with respect to the load of respirators and the chosen loading configuration. Recommendations for parameters of dry heat sterilization cycles. The well-established recommendations for parameters of dry heat sterilization cycles (= time / temperature integral) are: ► 180°C for 30 minutes according to WHO or ► 160°C for 120 minutes according to European Pharmacopoeia Basically Memmert sterilizers type S are able to perform these sterilization cycles as any other tailored sterilization cycle by routine (time variable, temperature up to 250°C) as a result of sterilization process validation by routine. However, with respect to the well-established parameters and in order to implement more of a safety margin we recommend using: ► 180°C for 60 minutes or ► 160°C for 240 minutes
