Reagents

[Ame]

I have my TFtest TF100 kit from last year. How long do the reagents accuracy last? Do I need to replace them yearly?

Depends on how you stored them. If they were stored in the climate controlled house out of the sun, they are likely fine.

The answer is maybe and that's final!

I keep my kit indoors and I have no problem using whatever reagents. Some might be over a year old. Who knows? Look at the bottles. If they're not discolored, things are probably okay. And if your readings are about what you think they should be, I wouldn't worry.

I keep mine under the sink, on a shelf except when I'm using it.
