    The TF Test Kit uses Taylor reagents. Taylor only rates their reagents for one year. However, stored in a cool dark place everything in the test kit should last at least two year and quite possibly longer.

    Hi Jason,

    My order for the TF-100 is plenty of back up reagents. Since my ambient temp here is high, will it help if I put in a refrigerator at 4 deg celcius ?

    It's not just temperature but the chlorine test reagents are ruined by light, moisture (for the DPD powder), and oxygen. All the other reagents in the kit should last at least 2 years or more if not stored under extreme conditions. the DPD powder and FAS titrant are the ones with the short shelf life.
