    How long do test chemicals last?

    I ordered a TF-100 test kit two years ago and have had great luck with it. However, I was wondering how long the various chemicals in it last? Do certain chemicals in it expire and need to be reordered? Thanks in advance!

    While there is no expiration date, I would say that two years is pushing the envelope a bit.

    As a follow up to this, if I just bought a new kit today, and I have chemicals left in the fall. Assume I store them properly, do I really need to replace next May or will they last through the 2014 season and I replace AFTER 2 years.

    Is there a way to tell if bad or not ?
