    frozen reagents

    I accidentally allowed some reagent bottles to partially freeze. Among those frozen are a nearly empty bottle of R-0004-E which I won't cry over, half a bottle of R-0871-E, 3L of R-0013(G), and possibly a couple of R-0009-C's (didn't actually check them). Nothing froze completely, and they are being thawed slowly at a cool room temperature (still have an iceberg in them after a full day).

    Are they still any good after being partially frozen?

    you probably should toss them, but I find that sunlight exposure kills reagents more so than temp. You could always compare your results with another test kit (maybe a neighbor or a pool store?)

    These are refill bottles for my nine test kits around town. I guess I can find clean empty bottles and test them...good idea.
    Will report!

    Re: frozen reagents

    Any liquid that has frozen
    A liquid reagent may still be effective after freezing. Allow it to thaw at room temperature. If the bottle cracks, if you see a crusty buildup around the dropper tip, or if there are floating particles that do not dissolve when the bottle is shaken, replace the reagent.
