R-0013 (CYA Reagent) Expiration Date

[DanF]

I'm out of the three 2-oz bottles of CYA reagent that came with my K-2006C test kit. So I ordered an 8-oz refill bottle from TFTestkits.net. However there was no expiration date on the refill bottle, but my original reagents in the 2-oz bottles had an expiration date. Should I be concerned? Does R-0013 expire?

Not really. Unless it is contaminated. Freezing it might mess it up. It is the most stable reagent in pool water testing.
