[labnetwork] Nanostrip/Purestrip bottle leakage: what do most labs do?

[Beaudoin, Mario]

Dear Labnetwork,

As many labs do, because of safety concerns for the students, I banned 
the use the real pirahna etch in favor of Purestrip (Transene version of 
nanostrip).  The problem I have is that the solution eventually leaks 
from the bottle.  I have heard of others mentioning this also.

I am now thinking of revising this policy and going back to old pirahna, 
despite the issues with safety and aging H2O2.

Anyone have comments?

Mario
