H2O2 bottles - watch out for breakage

2006-05-08 by Stefan Trethan

Today when moving my bottle of H2O2 (35%) i noticed a strange cracking  
sound when pressed on.
Closer inspection shows the inside of the bottle is cracking, the inside  
of the wall must have hardened and gone brittle.
The outside seems still fine, but of course this wants a new bottle ASAP.
This one is PE (polyethylene) and 3 years old (only once refilled).

So watch out - we don't want no silly accidents with a liter of 35% H2O2  
running out of a crack and over your hands....

Mailed the chemicals shop what to do about it, which bottle to use, will  
see what they say.

Wouldn't glass be a fairly safe bet with most chemicals?

Basically i would hope so.
But google says:

"Hard glass like Pyrex must be used in storing H2O2, in order to prevent  
hydrogen peroxide from decomposing by effluence of glass constituents.".

Now i have a small amount of H2O2 in a glass bottle and it seems just  
fine. Anyway i'll wait what the chemicals shop says tomorrow, after all  
it's their job to know such things....
