[Histonet] RE: picric acid

[Goins, Tresa]

The picric acid around the cap would not be "1%".  The acetone is long gone.  Wipe the threads or pipette the reagent from the bottle.
Our chemical safety office informed us that friction from removing a cap can be enough to set it off.

I am curious how big an explosion there would be from 1% picric acid in acetone if a little dried around the cap.
