Hanna HI718-25 Iodine DPD method reagents

Hanna HI718-25 Iodine Checker HC Reagents – 25 Tests DPD Method

The Hanna HI718-25 reagent set contains 25 high-quality, pre-measured packets specifically designed for use with the HI718 Iodine Checker HC. These reagents utilize the DPD (N,N-diethyl-p-phenylenediamine) colorimetric method, in which iodine reacts with the reagent to produce a pink tint. The Checker HC measures the intensity of this color to determine iodine concentration in ppm (mg/L).

Each packet is clearly marked with a lot number and expiry date to ensure full traceability, quality control, and reliability—ideal for drinking water analysis, disinfection monitoring, and water quality testing in both lab and field settings.

Features

• Pre-Measured for Accuracy: Each sachet contains the exact amount of reagent needed for a single test, reducing user error.

• Fast & Reliable Readings: Designed to deliver accurate iodine measurements in under a minute using the HI718 Checker®.

• Trusted DPD Method: Based on the proven DPD colorimetric method for iodine detection.

• Traceable & High Purity: Reagents are manufactured in a temperature-controlled environment using reagent-grade chemicals.

• Long Shelf Life: Clearly labeled with expiration date and lot number for quality assurance.

Best Practice Tips for Accurate Results

• Ensure the sample is free of debris before testing.

• Wipe the outside of the cuvette thoroughly with a lint-free cloth (e.g., HI-731318) to remove fingerprints or oil.

• Avoid bubbles: Do not shake the cuvette; gently swirl or tap to remove air bubbles.

• Take readings immediately after the reaction—delays may compromise accuracy.

• Discard the reacted sample immediately after testing to avoid staining the cuvette.
