CAUTION
LOW SURFACE TENSION LIQUIDS
– ORGANIC SOLVENTS
The probes (solid or w it h a replaceable t ip) are tuned element s t hat resonate at a specif ic f requency.
If t he replaceable t ip is removed or isolat ed f rom t he rest of the probe, the element w ill no longer
resonate at that f requency, and the pow er supply w ill f ail. Unlike aqueous (w at er based) solut ions
w hich rarely cause problems, solvent s and low surface t ension liquids are problemat ic. These liquids
penet rat e t he
probe/replaceable t ip interf ace, and force t he part iculates into the t hreaded sect ion isolat ing the t ip
