Taylor DPD Titrating Reagent R-0871-E 16 oz Liquid — Chlorine Titrant for Pool & Spa Testing

This reagent from Taylor Technologies is made in the United States and supplied in a 16 oz liquid bottle designed for routine and professional water testing. It pairs with DPD indicator procedures to quantify free and total chlorine levels via titration, offering a dependable chemical standard for pool, spa, and industrial water analysis when used according to instructions.

How does this reagent fit into a DPD titration workflow?

The R-0871-E serves as the titrating solution that reacts with DPD-developed color in sample vials to indicate the endpoint during chlorine measurement. When added dropwise to a prepared sample, it neutralizes the colored complex until the solution clears, allowing concentration to be read from the titration volume or test kit scale.

• Compatible with DPD-based titration kits and procedures.
• Used dropwise to reach the visual endpoint of the DPD color change.
• Packaged in a 16 oz bottle for multiple tests before replacement.
• Intended for professional and routine water testing settings.

What performance or handling details should I know?

R-0871-E is supplied as a liquid reagent that should be stored and handled following safety guidance and kit instructions. Keep the bottle capped when not in use, store at recommended temperature ranges, and discard according to local chemical disposal rules when depleted.

• Store upright with cap tightly closed to preserve stability.
• Follow supplier or kit instructions for accurate dosing and endpoint determination.
• Observe standard lab safety: gloves, eye protection, and spill cleanup procedures.
• Manufactured in the United States, model R-0871-E by Taylor Technologies.

How much reagent will I need and how long does one bottle last?

One 16 oz bottle provides enough titrant for many tests, but actual test count depends on sample chlorine levels and volume used per titration. Low-chlorine samples require fewer drops per test, extending the bottle life, while high-chlorine samples consume more reagent per determination.

• 16 oz volume suitable for frequent testing programs.
• Test consumption varies with typical sample concentrations and kit drop size.
• Plan replacements based on your testing frequency and average chlorine levels.
• Keep inventory of spare bottles for uninterrupted testing schedules.

Who is this for: Taylor R-0871-E is aimed at pool and spa service technicians, public facility water testers, industrial water treatment operators, and laboratory technicians who use DPD titration methods and need a consistent, ready-to-use titrant. It is not a standalone test device; use it as part of a DPD titration kit and follow kit protocols and safety data sheets for proper and safe application.
