    Length reagents last

    I'm curious about this as well and wondering which test last longer than others. I'm hopeful I don't get yanked for hijacking a thread but the question has already been asked by the OP.

    Re: Length reagents last

    The reagents most susceptible to going bad are -

    R-0870 (DPD Powder)
    R-0871 (FAS Titrant)
    R-0011L (CH indicator)

    Those three can easily go bad from moisture and heat. All of the other reagents are fairly stable and can last quite a long time. Taylor gives a 1 year timeframe mostly as a warranty - they are basically saying that their reagents will work, as expected, for one year. Beyond that, you're on your own.
