    How long will R-0871 titrating reagent last?

    how many seasons (years) will this reagent last stored indoors, climate controlled?

    i read somewhere that storing it in my fridge will prolong its life. is this true?

    I ask because I bought a 16 oz bottle. obviously that will last me 4 or more seasons, depending how many times I mess up and have to SLAM..... which I hope isnt much.....

    also, how do you know if it went bad? does it react different or does it change color?

    thanks!

    Not sure about the fridge storage, but generally we say two years for all reagents when stored inside.

    well, hopefully I can get longer than that. i plan on using the 16 oz bottle to refill two .75 oz bottles in my kit. so it will stay in fridge unless im refilling the bottles.

    how do I know if it went bad?

    R-0871 is unlikely to last more then two years or three years. For long term storage, uniform temperatures are more important than being especially cool. Do not store the bottle that is in active use in the fridge, the frequent temperature changes from going in and out of the fridge can cause it to go bad. It should be a clear colorless liquid. If it turns a dark yellow color, it has gone bad.

    Once it has gone bad how does it affect the testing? Will it show too low, too high...or just plain unreliable and wacky? I've always wondered...

    When it is just starting to go bad it will read false high, but once it goes completely bad the sample will never turn clear.
