Quick overview
- Free chlorine reagent The DPD 1B liquid used in the LaMotte free chlorine test.
- Thirty milliliter bottle Supplied as a 30 mL bottle, the standard refill size.
- Genuine LaMotte Part P-6741-G from LaMotte, the water testing manufacturer.
- Refill, not a whole kit Buy the one reagent that ran out rather than a complete replacement kit.
- Pairs with DPD 1A LaMotte lists DPD 1A alongside it, and kits that call for 1B normally use both.
- Keep it fresh Reagents age, so a kit that reads oddly is often carrying a bottle that is past its useful life.

Product details
LaMotte P-6741-G is the DPD 1B free chlorine reagent, supplied in a 30 mL bottle. It is the refill for LaMotte pool water test kits that use the liquid DPD 1B.
Buy the bottle, not the kit
Reagents get used at different rates, and the chlorine bottles usually empty first because chlorine is the test people run most. Ordering the single reagent that ran out keeps a good kit in service instead of replacing the whole thing.
Keeping results honest
Liquid reagents age, and an aged bottle will quietly give you readings that look plausible but are not. If a kit that used to agree with your service tech has started to drift, fresh reagent is the cheapest thing to rule out. LaMotte lists DPD 1A in the same size, and tests that call for 1B typically use both.
