DPD Free Chlorine Reagent Powder YSI PhotoFlex & 900 Colorimeter 10ml

Description

Product Overview

The YSI DPD Free Chlorine Reagent Powder is a high‑purity analytical reagent formulated specifically for use with PhotoFlex and 900 series colorimeters. Each vial contains 10 ml of reagent, calibrated to deliver accurate free chlorine measurements across a broad analytical range of 0.02 to 2 mg/L. The powder is EPA approved, ensuring compliance with environmental testing standards and providing confidence for laboratories, water treatment facilities, and field technicians. Its compact packaging minimizes storage space while protecting the reagent from moisture and contamination.

Usage

This reagent is ideal for routine water quality monitoring in municipal drinking‑water systems, wastewater treatment plants, and industrial cooling‑tower circuits. Users simply add the powder to a measured volume of sample water, allowing the DPD reaction to develop a distinct color that the colorimeter quantifies. The reagent works reliably in a variety of sample matrices, including turbid water, chlorinated pools, and environmental runoff. Its fast reaction time and stable color development make it suitable for high‑throughput testing environments where rapid turnaround is essential.

How often should the reagent be calibrated?

Calibration checks are recommended monthly or whenever a significant shift in measurement results is observed. Use a certified chlorine standard to verify accuracy.

Is the reagent safe for handling?

The powder is non‑hazardous under normal laboratory conditions. However, standard safety practices such as wearing gloves and eye protection are advised to avoid accidental contact.

What is the shelf life of the 10 ml vials?

When stored properly, the reagent maintains its performance for up to 24 months from the date of manufacture. Always check the expiration date printed on the packaging before use.
