Cleaning the glass capillary
Yes, it was on
Consider different resonance of metal and glass in ultrasound
I have at least another one capillary died with sonication (became worst
than been before)
Currently we do not sonicate, only soak and wash and capillaries last (I
have one with 3 succesful washes)
I would not recommend sonication for a metal plated glass capillary. It seems damaging it.
I had platinum plating chipped off from a hexabore capillary after sonication.
Just soak in detegent, then wash with water, then 50-50 org-water then organic solvent
