CYA R-0013 Reagent question

[hensler74]

Hello all. I have a partial bottle of the R-0013 reagent TF brand and it is not enough to do a CYA test. I have a brand new bottle that used to test with. My question is since they are both the TF brand can I add the partial bottle to the bottle I just opened and tested with or is this not wise.

R-0013 is very stable over time. On your next test, use the older R-0013 first and top up with the new R-0013 to do that single test. This way, it is only 1 test that you have the combined reagents.
I would NOT pour the old into the new as that mixes the total bottle.

Thanks that is what I will do.
