    From what I read the only reason there's two are because the chlorine only one tends to get a black ring on it. Other than that....yep you're fine.

    Leebo has it absolutely correct. They are identical but the FAS/DPD test tends to leave that residual black ring which may or may not cause just a little interference on the other tests.

    Double or triple rinsing before and after testing can help reduce vial staining and cross contamination of other tests.
