5.2 Treatment of contaminated parts in the ultrasonic transducer, vesselsand accessories pertaining to the medical fieldWhen working with ultrasonic homogenisers, the sonicating parts, vessels and other accessories(e.g. stands, mounting tools) could become contaminated with microorganisms or toxicologicalagents and lead e.g. to cross-infections. Disinfection and/or cleaning is required.In the event of incorrect or irregular disinfection and cleaning, contamination is possible, especiallyat the connecting points (e.g. between titanium plate and standard horn) and at the sound-emittingsurfaces (see chapter 5.1 , Wear).Therefore, the sonicating parts (such as the standard or booster horn, micro tips or tapered tips,and titanium plates), vessels and accessories should be disinfected and cleaned after every use,and dismounted for this purpose if necessary.In the event of toxic contamination, the applicable regulations and provisions of BGR 250/TRBA250 are especially to be observed.The disinfection and cleaning should be performed regularly by the operator, if applicable inaccordance with the hygiene plan and using a VAH-certified or other effective surface disinfectant.Note:Additional information and provisions locally applicable at the user's/operator's site must beobserved.5.3 Warehousing / storageDuring extended periods without use, the homogeniser should be stored in a cool, dry place.The ultrasonic transducer should be covered in order to protect the electronics from outsidecontamination.28 / 44 51436a GB/2017-101 electronic GmbH & Co.
