  • Free chlorine reagent The DPD 1A bottle used for the free chlorine step of a LaMotte test.
  • Genuine LaMotte Part number P-6740-G, the factory refill rather than a generic substitute.
  • 30 mL bottle The standard refill size, so you replace one reagent instead of buying a whole kit.
  • Used with DPD 1B DPD 1B is a separate 30 mL bottle and is sold on its own.
  • DPD 3 is separate The DPD 3 reagent used for the combined and total chlorine step is a different part.
  • Reagents age Test chemicals lose accuracy over time, so a fresh bottle is the first fix for readings that no longer look right.

Product details

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.
