Packaged in a 16 oz bottle and made in the United States, the R-0871-E provides the active chemistry needed to produce a clear titration endpoint when used with the appropriate DPD indicator and titration technique. It is compatible with standard titration kits and procedures that specify FAS-DPD reagents.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the R-0871-E reagent function in a chlorination test?\u003c\/h3\u003e\n\n\u003cp\u003eThe R-0871-E serves as the titrant in the FAS-DPD method: it reacts with the DPD-stained sample to reduce chlorine until the DPD color disappears, indicating the endpoint. The volume of titrant used corresponds to chlorine concentration and is converted to mg\/L or ppm using the test kit's calculation or graduations.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eFormulated for use as the ferrous ammonium sulfate (FAS) titrant in DPD titrations.\u003c\/li\u003e\n  \u003cli\u003eUsed with DPD indicator tablets or solutions that create a pink to purple color proportional to chlorine.\u003c\/li\u003e\n  \u003cli\u003eMeasures free and total chlorine depending on sample preparation and DPD use.\u003c\/li\u003e\n  \u003cli\u003eCompatible with manual titration kits and glassware commonly used in pool, spa, and water testing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the storage and handling considerations for this 16 oz liquid reagent?\u003c\/h3\u003e\n\n\u003cp\u003eStore the R-0871-E in a cool, dry place away from direct sunlight and heat sources, tightly capped to maintain reagent stability.
