5.2 Treatment of contaminated parts in the ultrasonic transducer, vessels
and accessories pertaining to the medical fi eld
When working with ultrasonic homogenizers, the sonicating parts, vessels and other accessories
(e.g. stands, mounting tools) could be contaminated with microorganisms or toxicologic agents
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, especially
at the connecting points (e.g. between probe and ultrasonic transducer) and at the sound-emitting
surfaces (see chapter 5.1, Wear).
Therefore, the sonicating parts (such as the probes), vessels and accessories are to be
disinfected and cleaned, and dismounted for this purpose if necessary, after every use.
In the event of toxic contamination, the applicable regulations and provisions of the BGR 250/
TRBA 250 are especially to be observed.
The disinfection and cleaning should be performed regularly by the operator, if applicable in
accordance with the hygiene plan and using a VAH-certifi ed or effective surface disinfectant.
Note:
Additional information and provisions locally applicable at the user’s/operator’s site are to be
observed.
5.3 Warehousing / storing
During extended periods without use, the homogenizer should be stored in a cool, dry place.
The ultrasonic transducer should be covered in order to protect the electronics from outside
contamination.
