Any tips or ideas to clean Activated Carbon out of the fritted disc of the buch funnel ?

[MissionAcomplished]

at what temp does the carbon get destroyed ?

[MagisterChemist]

I’m not really sure. I’d say as hot as you can go.

I would start with a soak in iso first. Then go to a stronger chem.

Tricks of the trade

Good call…here is a little more detail. Qaulity glassware shouldn’t require vacuum grease. cleaning with a good sprayer makes things a bit easier. The nozzle can go further in the glassware. Setting on spray/mist by inserting in the neck of the flask washes of the sides. [image] Avoid sonicating glassware. Over time it will weaken the glass. Wrap a stir bar in a scrubby and put on stir plate to get off nasty tar.
