Cleaning agents which extract the plasticizer from the plastic are never to be used for plastic probes
(practically all solvents!).
We recommend the following for cleaning the probes:
• running water
• soapy water
• pure benzene
Cleaning example:
1) Carefully swish the top part of the impeller back and forth in clean, pure benzene for ca. 10 min. Then
swish the top part of the impeller back and forth in clean kerosene for ca. 1 min. to relubricate the impeller
bearings.
If soapy water is used as a cleaning agent it is advisable to wash out the soap solution thoroughly with
distilled water before lubrication with kerosene.
2) After cleaning the probe, rub it dry externally with a clean, dry, fluff-free cloth.
3) Leave the top part of the impeller to dry for ca. 30 minutes.
