Sonotrodes transfer the mechanical vibrations into the sample, are thermostable, autoclavable and resistant to corrosive media. Sample volume, vessel diameter and desired amplitude determine device selection and sonotrode type. A high amplitude means a particularly intensive sonication. The sonotrode is connected to step or booster horns. All BANDELIN sonotrodes are made of the titanium alloy TiAl6V4 (3.7165).
