- Every (non-Lexan) Nalgene bottle I've owned (and I've had lots of
them) eventually breaks down and disintegrates. They turn yellowish
and brittle, and show a crazed appearance. At that point you can
crush them in your hand. I've probably thrown out a dozen and a half
of them over the years.
Oddly, the caps are fine.
The one in the pack was old and likely as not suffering from this
malady. Still, it's weird that the glass vial survived while it
I've been told that Nalgene's plastic *used* to not be UV stabilized
and now is. The curious thing about this theory is that many of the
little bottles I've had fail spent 99% of their lives in storage or
inside a pack--safe from any UV exposure. I certainly hope labs using
Nalgene to store their hydrofluoric acid haven't had similar
My idle speculation is that Nalgene, as a lab supplier, has always
primarily been concerned with formulating their containers to not
contaminate their contents. It does seem to be the case that they
don't flavor water like many other plastic containers do. This *may*
mean that their are strength and longevity tradeoffs as a result.
