    Expiration Date of Test Reagents

    I bought a TFT-100 reagent refill pack last year and have a good bit left for this year. Are the reagents still good? How long can I get reliable test results before I should toss them and buy a new set of refills? Thanks for all the good advice!

    The reagents for the TF-100 are warranted to be viable for 18 months from the date of purchase. You should be good to go.

    Typically, we suggest replacing reagents every 2 swim seasons (although some, given proper care will last longer).

    Taylor warrants their reagents for one year from when that lot was manufactured.

    There is a sticky around here somewhere showing how to determine if they are good and how to do the test/how to store, I believe jasonlion wrote it. I'll try to find it.

    Expiration signs are sort of buried in his posts, but a lot of good info here.
