Product details

This is the LaMotte DPD 1A free chlorine reagent, part number P-6740-G, in a 30 mL bottle. It is the genuine LaMotte refill for the free chlorine step of a pool water test.

Buying reagents on their own

Reagents run out at different rates depending on which tests you run most, and they do not last forever once opened. Buying the single bottle you are short of is cheaper than replacing a whole kit, and it keeps the rest of your reagents on their own replacement cycle.

The rest of the set

DPD 1B is a separate 30 mL bottle, and the DPD 3 reagent used for the combined and total chlorine step is a different part again. Check your test procedure and order whichever of them you are low on at the same time.
