That depends on the definition of what's useful. For sterilization,
the GTA solution has to be pH about 8, but at that pH, GTA polymerize
and becomes ineffective, at least for sterilization purpose.

At acidic pH, polymerization is greatly slowed down and shelf life
expanded.

What do you use it for?

Right, but do it with care.
(What I meant is that if you buy more dilute stock, risk is also lowered.)
