ABSTRACT:
An ultrasonic sonotrode for irradiating ultrasonic energy into fluid or pasty media, wherein the ultrasonic sonotrode in the longitudinal direction (z) includes: a coupling section for coupling an active ultrasonic system which excites longitudinally in the longitudinal direction (z); a base section, wherein the largest dimension of the base section transverse to the longitudinal direction (z) is larger than the length of the base section in the longitudinal direction (z), wherein the dimensions of the base section transverse to the longitudinal direction in the border region to the transition section are always ≧λ/4 and the shortest length of the base section in the longitudinal direction (z)<λ/4; a transition section for the reduction of the cross section in at least one cross-section with respect to the base section; and a flat section with an end-face region as an irradiation surface, wherein the flat section is divided by way of at least one slot into several tongues which are unconnected in the end-face region.
