Taylor Kit Left out all winter

[CarlD]

You COULD try using them and see if the results make sense. I don't know which chems freeze and which are so saturated they don't freeze. You FAS-DPD powder should be fine. You ARE supposed to store the kit in a cool, dark dry place, but below freezing may not be good.

But try them first and replace what's bad.

You can see how to Recognize a Compromised Reagent. Freezing is not good, however. As for shelf-life of reagents when maintained in a cool dark place or no worse than room temperature away from sunlight, this post gives a rough shelf-life.
