6 Maintenance
6.1 Cleaning the device
• Disconnect the device from the mains before cleaning.
• Wipe the device with a lint-free damp cloth. You can use a commercially avail-
able cleaning agent without abrasive additives.
• If necessary, the surfaces can be treated with a surface disinfectant.
• Clean the probe with a cloth soaked in alcohol.
• The probe can be processed in a steriliser. Unscrew it before cleaning.
6.2 Refurbish probe
The probes are subject to erosion on the sound-emitting surface. This leads to a
reduction in sonication efficiency.
The sound-emitting surfaces can be carefully polished or milled a few times.
You can process the surface using a grinder with a fine grinding disc or by hand
with a diamond file.
Suitable grinding materials are, for example:
• Fine abrasive wheel, polyurethane-bound – grain size 150
• Fine abrasive wheel, rubber-bound – grain size 120
• Grinding wheel PNK, corundum – grain size 180-280
• Diamond file, D 181 or D 251
As soon as material removal due to erosion or rework exceeds a value of approx.
1 mm, the probe can no longer be used. Amplitude or power is then no longer dis-
played on the touchscreen. In the case of frequent use, it is recommended that an
inventory supply of probes be kept.
