Free and Total Chlorine (Low, Medium and High Range) Test Kit Replacement Reagents (200 tests HI38020-200
The HI38020-200 are replacement reagents for the colorimetric determination of free and total chlorine with the HI38020 Free and Total Chlorine Low, Medium and High Range Test Kit. There are enough reagents for approximately 200 tests to be used with Hanna's test kit. These high quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.
- Pre-made reagents for ease of use
- Prepared with high purity chemicals
- Marked with expiration date and lot number for traceability
The HI38020-200 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate free and total chlorine measurements with the chemical test kit. These reagents follow the DPD (N,N-diethyl-p-phenylenediamine) method to determine free and total chlorine concentration.
For determination of free and total chlorine, the appropriate DPD powder reagent is added to a sample containing chlorine. The reaction between chlorine and the reagent causes a pink colored complex to form; the greater the concentration, the deeper the color. A Checker Disc is included for an accurate, side-by-side, visual analysis to determine free and total chlorine concentration. These reagents are designed to be used with low, medium, and high range samples that have expected free and total chlorine ranges of 0.00 to 0.70 mg/L Cl2, 0.0 to 3.5 mg/L Cl2, and 0.0 to 10.0 mg/L Cl2, respectively.
