Beam diameter 19 mm, suitable for SH 200 G (HD 4200). Sonotrodes transfer the mechanical vibrations into the sample, are thermostable, autoclavable and resistant to corrosive media. Sample volume, vessel diameter and desired amplitude determine the choice of instrument and type of sonotrode. 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).
