The contact liquid in the ultrasonic bath must be regularly replaced.
Layers of contamination on the tank bottom reduce the ultrasonic output.
The oscillating tank is to be emptied and cleaned after a long period of use or sonication
of heavily soiled objects. For additional information, see chapters 4.5.3 and 5.1.

(without ultrasound). The integrated pump starts working automatically and thoroughly
fl
ushes the ultrasonic bath.
