Does Hielscher offer replaceable sonotrode tips?
Hielscher does not supply replaceable tips for sonotrodes. Low-surface tension liquids, such as solvents typically penetrate the interface between the sonotrode and the replaceable tip. This problem increase with the amplitude of oscillation. The liquid can carry particulates into the threaded section. This causes wear at the thread leading to an isolation of the tip from the sonotrode. If the tip is isolated it will not resonate at the operating frequency and the device will fail. Therefore Hielscher supplies solid probes, only.
